I had to make a change[1] to the Linux UT99 binary during install to
stop it from attempting to use FreeBSD's libGL.so due to its hard-coding
of LD_LIBRARY_PATH.  It may be evil, but it worked.  :)

Once my system's SATA DVD drive works with RELENG_7, I will try to see
if I can fix linux-nwnclient.  Skype may have the same "solution".

Mike, I Cc'd you to see if you can try using sed like I did in the
linux-ut port to "fix" nwmain.  Using strings, you can see if
/usr/local/lib is hard-coded into the binary and replace it with an
equal length string that does not point to anything.
