It has worked well for me, but I see your point. I think it works as
long as you don't have conflicting possibilities - e.g. I recently
ran into trouble on a Solaris box because there was an ancient GDAL
lying around in one of the search paths, conflicting with the modern
version I installed.

Yes, I've done that too - the mix is a result of some experimentation
- I see the danger, and I don't recommend the mixed method to those

Oops, how embarrassing. I knew that at one point, but forgot while
doing this, and copied my configure options over from a 6.3 build.

Between this and Agustin's post, this sounds promising. The machine
in question is at home and turned off, but I'll try it out ASAP.

OK, that's clear. I prefer the X11 version myself anyway. Now I
realize my problem was just that I was using a 6.2 source tree, not a

I have done both, depending on the machine and how much I interact
with it. I have /usr/local/tcltk on other machines. I've had no
trouble either way most of the time.

Yeah, I was worried about that. I've committed a change to tcltk.php
accordingly, but if you want to clean up those pages yourself, I'll
hold off other edits.
Thanks, it's great to see the logic!
