Ok, it seems that I should slightly expand my explanation.
The xforms libraries comes only in binary form but author was stupid enough to
compile shared library with "-soname libforms.so", while the library is installed
under libxform.so.1 name. Therefore after you linked it dynamically the resulting
executable appears to be linked with nonexisting libform.so shared library.
$ echo 'int main() {}' > x.c
$ cc x.c -o x -L/usr/X11R6/lib -lxforms -lX11 -lm
$ ldd x
x:
libforms.so => /usr/X11R6/lib/libforms.so (0x28064000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x28135000)
libm.so.2 => /usr/lib/libm.so.2 (0x28226000)
libc.so.4 => /usr/lib/libc.so.4 (0x28241000)
libc.so.3 => /usr/lib/compat/libc.so.3 (0x282d1000)
