My machine does not have X11 installed, and I have '-X' in my USE flags.
However compiling mjpegtools 1.6.2 gives the following error:
(cd .libs && rm -f liblavplay.la && ln -s ../liblavplay.la liblavplay.la)

Reproducible: Always
Steps to Reproduce:
1. emerge unmerge xfree86
2. ACCEPT_KEYWORDS="~x86" USE="-X" emerge mjpegtools
3.
seems to be a problem with configure.in -- it checks if X_DISPLAY_MISSING is
defined in X_CFLAGS, but it should probably check CFLAGS or some other
variable.
observe my config.log excerpt:
| #define HAVE_LIBDL 1
| #define HAVE_LIBDV 1
| #define X_DISPLAY_MISSING 1
| #define HAVE_X 1
| #define HAVE___PROGNAME
| /* end confdefs.h. */
so it notices that X is missing, but the test for X_DISPLAY_MISSING didn't
execute correctly, so it set HAVE_X. Here is the relevant configure.in code:
dnl *********************************************************************
dnl Lets find where xwindows lives on this machine. Punt if not found.
AC_PATH_XTRA
have_x=false
if test x"-DX_DISPLAY_MISSING" = x"$X_CFLAGS"; then
AC_MSG_WARN(can not find X11)
else
have_x=true
AC_DEFINE(HAVE_X, 1, [Whether XFree86 is available])
fi
AM_CONDITIONAL(HAVE_X, test x$have_x = xtrue)
