Hi Brian,
I wouldn't doubt that this is a path issue. The other path issues
that I've had installing python and then the requisite libraries seems
to be endless. I'm using Mac OSX.4, a Powerbook but not an
Intel-based Mac (as far as I know... its several years old).
My ~/.profile is actually empty. A while ago, I left a note in this
file that all of the terminals are controlled by the /etc/bashrc file.
I tried sourcing this file, but to no avail.
It appears that I need to add LaTeX, dvipng, and ghostscript to my
path. I installed LaTeX and ghostscript using iInstaller and run TeX
through a front end (AlphaX) that does all of the typesetting for me,
so I'm woefully ignorant of the paths for any of these utilities. I
installed dvipng very recently, so I assume it went to the default
location. I have two questions:
1) How do I determine the paths of these utilities?
and
2) How do I add them to the PATH variable? Should I put this in a
configuration file somewhere so that I don't have to do this
repeatedly?
Thanks for the quick responses, and sorry about the ignorant questions,
Adrian
