We link to libcrypt because it provides crypt(), at least on GNU

and on the FreeBSD libc; it seems not the case on Mac OS X, looking
at your patch.
I'd say that this should turn into a proper configure check, trying to
use crypt() without extra libraries and if not possible with libcrypt.
The crypt() thing is explained here:
https://developer.apple.com/library/mac/documentation/Porting/Conceptual/...
(Compiling... in OS X -> Other Porting Tips -> Functions -> crypt).
(TL;DR: crypt() comes from unistd.h)

Is setting LD_LIBRARY_PATH somehow harmful/problematic on Mac OS X?
If not, I'd say to use a variable for the library paths we want to add,
then adding them to both LD_LIBRARY_PATH and DYLD_LIBRARY_PATH;
something like
libdirs="$b/src/.libs:...etc"
# Set LD_LIBRARY_PATH to contain library.
if [ -z "$LD_LIBRARY_PATH" ]; then
LD_LIBRARY_PATH="$libdirs"
else
LD_LIBRARY_PATH="$libdirs:$LD_LIBRARY_PATH"
fi
export LD_LIBRARY_PATH
# ditto for DYLD_LIBRARY_PATH
You'll end up with two semi-identical blocks of code, though, because
you'll have to perform the same -z check for DYLD_LIBRARY_PATH. (As
far as I am aware, Darwin does not use LD_LIBRARY_PATH, hence the
substitution.)
