Hi, im trying to install libxml2-2.6.18 from the FreeBSD ports, there is a problem with the compile on
the system i am using. I have tried several versions of libxml2 and they all return the same error, which
means its probably not an issue involved with libxml, but I cant pin down where the error is coming from,
or what is causing the problem to occur. I was hoping someone on this list would be able to point me in
the direction of what is causing this.
The error is:

Well, you should search for _signbit or signbit, since the compiler
may have prepended the _ for a static/private variable.
Somehow your system or compiler includes are not in synch with your
installed libc, sounds bad, but you're right it doesn't sound like a
libxml2 problem.
Creative use of nm -o on each of the binaries should show which one is
calling for it, and may help. Also make sure you can compile a simple
test program, e.g.
#include <stdio.h>
main()
{
printf("hello world\n");
}
with (if it's in hello.c) gcc -o hello hello.c
and then ./hello to run it.
If that fails, (it might produce warnings, but it should compile and
run!) then you should consider installing gcc agin from binary packages,
and get OS-specific help from someone.
