Well right now this does work because (I think) ldconfig *is* ran by=20
pkg_add (or make install) when installing the port, if it contains=20
shared libs.
I'm not sure I agree that searching /usr/local by default is violating=20=
PREFIX anymore, since /usr/local is usually our default prefix=20
(exception made of X) for ports.
The initial problem is that we have 4 PREFIXes in common installs: /,=20
/usr, /usr/local and /usr/X11R6. How is a port supposed to find a=20
dependent package in there? How can it pretend to be PREFIX-independant=20=
when the ports depending on it can be installed in one of these 4=20
different PREFIXes?
/usr/local is an interesting abstraction. It allows us to distinguish=20
base from ports, but it's basically a hack. We have "ports" (sendmail,=20=
openssh) in base, which blurs this line (and creates periodic threads on=20=
various mailing lists). Ideally, we should be able to have all of our=20
software cleanly packaged, base would only be "software packages written=20=
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=20=
default. But the ports system would need a bigger fence around it to=20
expose /usr this way, IMHO.
Unfortunatly, we're stuck with /usr/local, and I think that as soon as a=20=
port depends on another *port* its linking search path should be hacked=20=
to include the prefix of that dependent port.
No, I don't have any patches. ;)
