We do, too. We call it /site.

We go one step further... make sym links in /site/bin, /site/lib, etc.
that point into the "default" distribution dir.
Using your example,
/site/bin/latex -> /site/dist/teTeX/bin/latex
Then just make sure /site/bin is in your path (and /site/lib is in your
ldconfig search path, etc.).
If we want to allow users to run older versions, I usually have a
wrapper script that allows them to invoke latex-1.0.7, for instance.
Invoking latex would just give the default (usually most recent) version.

That's exactly what we do. But we added a .mk file which makes the
sym links described above, too, at install time. It's not perfect
yet, but with the 28155 patch what you suggested above works most of
the time. On occasion, I have to hack a makefile to, for instance,
define GLIB_CONFIG=/site/dist/glib-1.2.10/bin/glib12-config or some
other trickery since the Makefile and/or bsd.ports.mk system isn't quite
flexible enough. We have some patches for this, but have been waiting
(a while) for 28155 to be committed.

Yep, as I described above, sometimes you have to hack the makefile.
But most times, if /site/bin is in your path and /site/lib is in your
ldconfig search path, configure will find the right version and do the
right thing. If it doesn't work, it currently requires hunting down
which part of configure failed and why. That's a pain... it would be
nice if the ports tree supported non-default installation locations better
(i.e., not /usr/local).

Another thing that seems to work okay (if a port supports it - not too
many do - yet?) is pkgconfig (see devel/pkgconfig). It's kind of like the
*-config that some packages use (glib12-config, etc.) except more generic.
