.configure && make fails to find ld [dlopen]

[blubee blubeeme]

@Simon libdl is something used on Linux to provide dlopen like functions;
on FreeBSD it's already in libc so, removing the LIBS += -ldl removes the
problem and the program compiles successfully; I am just a bit lost as how
to proceed;

See my last email with the attached updated.diff file.

Best,
