Well right now this does work because (I think) ldconfig *is* ran by
pkg_add (or make install) when installing the port, if it contains
shared libs.
I'm not sure I agree that searching /usr/local by default is violating
PREFIX anymore, since /usr/local is usually our default prefix
(exception made of X) for ports.
The initial problem is that we have 4 PREFIXes in common installs: /,
/usr, /usr/local and /usr/X11R6. How is a port supposed to find a
dependent package in there? How can it pretend to be PREFIX-independant
when the ports depending on it can be installed in one of these 4
different PREFIXes?
/usr/local is an interesting abstraction. It allows us to distinguish
base from ports, but it's basically a hack. We have "ports" (sendmail,
openssh) in base, which blurs this line (and creates periodic threads on
various mailing lists). Ideally, we should be able to have all of our
software cleanly packaged, base would only be "software packages written
and/or maintained by FreeBSD", and would be a simple flag in the package.
Ideally, /usr/local should go away. Packages should install in /usr by
default. But the ports system would need a bigger fence around it to
expose /usr this way, IMHO.
Unfortunatly, we're stuck with /usr/local, and I think that as soon as a
port depends on another *port* its linking search path should be hacked
to include the prefix of that dependent port.
No, I don't have any patches. ;)
