The attached diffs
 - adds detection for the Xext and X11 libraries (which I think is a
must)
 - removes -ldl and -lpthread from some Makefiles (which I think is
_not_ the correct way, as autoconf should be taught about needing -ldl
or not, and about adding "-pthread" to the CC, CXX and LD flags when
required [e.g., on FreeBSD 4.x at least]). I'm willing to take a pot
shot at implementing that test, but I do not currently have a Linux or
older FreeBSD box to test it with.

Both diffs relative to todays CVS on cvs01.

With this magic:
env\
  CC="gcc -pthread" \
  CXX="g++ -pthread" \
  CPPFLAGS="-pthread -I/usr/X11R6/include -I/usr/local/include" \
  LDFLAGS="-L/usr/X11R6/lib -L/usr/local/lib" \
  CFLAGS=-I/usr/X11R6/include \
  ../blender/configure --prefix=/usr/local/blender --with-libpng \
  --with-libjpeg

I get a binary (which doesn't run because my X doesn't have the GLX
extension; off for a fun hunt in XFree42's bowels in combination with a
GeForce4 card :-)

Cheers,

If the only tool you've got is an axe, every problem looks like fun!
