You probably don't need -ldl (it's at the end of the line in ./build
that you're executing when it fails) so get rid of it and try again.
If FreeBSD is like OpenBSD (what I'm using just now), dynamic loading
is 'built in' so there is no /usr/lib/libdl.  If you're still stuck
tomorrow or Monday let me know and I'll get on a FreeBSD system at
work and look further.

By the way, I've never used ./build; I always edit config and run make
as I were on a Linux box.  In case you want to try that, here's some
diff output:
