Hi all,

I'm trying to get the beta version of AfterStep-1.5 running so that it'll
be easier for me to update the port when the real version comes out and to
check for any gotcha's.  I found one....  :-)

They are using a configure script to find -ljpeg and it's not finding it
on FreeBSD...   I'm sure it's due to the way we name the shared libs, but
I have no clue on how to fix the configure script so it finds it.  Below
is the bit of the configure script that does the -ljpeg test.  If someone
can help me to figure out how to get this straightened out I'd really
appreciate it!

Thanks a lot!

Brett
