I've forwarded the bug report to the upstream author and have suggested
the fix of replacing
export LD_LIBRARY_PATH=$VIPSHOME/lib:$LD_LIBRARY_PATH
with
export LD_LIBRARY_PATH=$VIPSHOME/lib${LD_LIBRARY_PATH+:$LD_LIBRARY_PATH}
which is the usual way that I deal with appending to colon-separated
variables. I haven't indicated where the bug has been forwarded to
since I just sent it personally to the author. They don't have a bug
tracking system, and I didn't mail it to the list....
