It's a little trickier than the way xaw3d handled it though.  A
half-dozen packages or more would use that directory and modify
ld.so.conf.

This is what I had in mind,

    /usr/lib/regina0/       -> contains scripts (external rexx functions),
                                e.g. http/ftp modules, Tk modules, &c
    /usr/lib/regina0/libs/  -> the packages would drop their libs in here

I guess on a package purge check if the libs directory is empty
and then remove the ld.so.conf entry. rpath seems cleaner though.

I saw a followup about the libc5 -> libc6 problem but I don't think
this is a problem with function libs/plugins is it?

[Sorry if I missed further followups.  @home mail is down again and it
will probably be a day before it's caught up. Pls Cc: replies to
this thread.]
