Fix:
Explicitly link to libm:
sed -i 's/^LIBS\s\+=.*/\0 m/' Makefile

What is the expected output? What do you see instead?
/usr/bin/ld: objs/astexpression.o: undefined reference to symbol 
'atan2@@GLIBC_2.0'
/usr/bin/ld: note: 'atan2@@GLIBC_2.0' is defined in DSO /usr/lib/libm.so.6 so 
try adding it to the linker command line
/usr/lib/libm.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make: *** [cfdg] Error 1


What version of the product are you using? On what operating system?
ContextFree 3.0 compressed tarball (v17)
Linux 3.4.6-1-ARCH #1 SMP PREEMPT i686 GNU/Linux
