General advice:

WATCH OUT for your init file! (~/.xemacs/init.el or ~/.emacs) If
you observe strange problems, invoke XEmacs with the `-vanilla'
option and see if you can repeat the problem.
+ Note that most of the problems described here manifest at RUN
+ time, even those described as BUILD problems. It is quite unusual
+ for a released XEmacs to fail to build. So a "build problem"
+ requires you to tweak the build environment, then rebuild XEmacs.
+ A "runtime problem" is one that can be fixed by proper
+ configuration of the existing build. Compatibility problems and
+ Mule issues are generally runtime problems, but are treated
+ separately for convenience.

* Problems with building XEmacs
===============================
** General
+ Much general information is in INSTALL. If it's covered in
+ INSTALL, we don't repeat it here.
+
+*** How does I configure to get the buffer tabs/progress bars?
+
+These features depend on support for "native widgets". Use the
+--with-widgets option to configure. Configuration of widgets is
+automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if
+you are using Xt and the Athena widgets, you will probably want to
+specify a "3d" widget set. See configure --usage, and don't forget to
+install the corresponding development libraries.
+
+*** I know I have libfoo installed, but configure doesn't find it.
+
+Typical of Linux systems with package managers. To link with a shared
+library, you only need the shared library. To compile objects that
+link with it, you need the headers---and distros don't provide them with
+the libraries. You need the additional "development" package, too.
+
*** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
without also using `-fno-schedule-insns'.
** Linux
+*** XEmacs crashes on startup, in make-frame.
+
+Typically the Lisp backtrace includes
+
+ make-frame(nil #<x-device on ":0.0" 0x2558>)
+
+somewhere near the top. One problem is due to an improvement in GNU
+ld that sorts the ELF reloc sections in the executable, giving
+dramatic speedups in startup for large executables. It also confuses
+the traditional unexec code in XEmacs, leading to the core dump. The
+solution is to use either the `--ldflags="-z nocombreloc" or the
+"--pdump" option to configure. "--pdump" is recommended.
+
+Recent 21.4 and 21.5 versions of XEmacs autodetect this feature of ld
+in configure. Unfortunately, Red Hat and SuSE (at least) distributed
+prerelease versions of ld (numbered around 2.11.90.x.y, nicknamed
+"Hannibal Lecter" at XEmacs.ORG) where autodetection fails but the
+feature is enabled by default. The recommended procedure is to
+upgrade to binutils >= 2.12 and rerun configure. Otherwise you must
+apply the flags by hand.
+
+Andrew Jaffe reported a problem on Red Hat 7.3 with identical
+symptoms, except that ld was already being invoked with -z
+nocombreloc. Switching dialogs and widgets from Motif to Athena
+eliminated the problem. Both LessTif and OpenMotif were installed,
+and a bad interaction is suspected. This problem has not yet been
+fully analyzed.

that esd is in fact running.
