Finally I understand the issue, I think.
But wouldn't an ordinary user on SCO wanting to install a private copy of
Pg then have to hack the Makefiles to change/remove the abolute DT_SONAME?
If so, that seems to me to mandate that this not be in the vanilla
distribution. OS Vendors commonly make changes like this in software
versions they distribute - that's a different thing from putting it in the
standard distribution, ISTM.
The benefit Larry cites seems to me to be small - presumably his Makefiles
must include "-L /usr/local/pgsql/lib", so adding
"-R /usr/local/pgsql/lib" doesn't look like a big thing. Adding an Rpath
to executables to use libs in non-standard locations is very common,
surely?
Maybe this needs to be YACO (yet another configure option)
cheers
