Ack.  You should not have to copy library files from /usr/X11* to
/usr/lib ... the compiler should include /usr/X11 in its path (of
places to look for libraries).  You can do this with something like:
        gcc -L/usr/X11R6/lib

Another thought hit me regarding the math library: is the /lib/libm.so
file that you have right now just a link?  Could you send the output
of an:  ls -l /lib/libm.so

I'm worried that maybe your real math library got trashed and so you
just have a dangling link pointing to it.  Otherwise (if it's a real
file), you're OK.  If a normal compile (well, link) fails because it
didn't find the math functions, add a "-lm" to the compile line:
        gcc -o file file.c -lm
