Glib has *nothing* to do with libc.

The latest version of FreeBSD libc is libc.so.5 (with 5.x). libc.so.6 is
also called glibc-2.x.x, and it's used for Linux. (You can find libc.so.6
in /compat/linux/lib).

You need to enable linux compatibility on your PHP extension.
Run `file /my/extension' -- if it says anything about ELF, run
`brandelf -f 3 /my/extension'. Now running `file /my/extension'
should return something like: [probably not exact]
/my/extension: ELF 32-bit LSB shared object, Intel 80386, version 1 (GNU/Linux)...
                                                The important part  ^^^^^^^^^^^

Hope this helps!
