Right now everything except vietOCR seems to be working just fine, and I don't want to mess it up. As far as computers go, I am "porting" from windows, and  just beginning to catch up on all the ins and outs of how linux does things, and sometimes it throws me a surprise....

Hopefully removing the software you have in /usr/local would not cause problems for software you installed using MacPorts, but I cannot guarantee that. The problem is that by installing software in /usr/local (whether by using Homebrew or other means), other software you build (including software build using MacPorts) may find that software in /usr/local and use it. This is why we do not support installing software in /usr/local while using MacPorts: because it leads to unpredictable results and sometimes problems.

I have never used Homebrew so I do not know how it works. I recommend you consult Homebrew documentation for instructions on how to uninstall Homebrew and anything you installed with it, if you would like to use MacPorts instead. Otherwise, consult the MacPorts Guide for instructions on uninstalling MacPorts so that you can instead use Homebrew.

> Generally I don't mind uninstalling homebrew, but I can see that usr/local/bin has some things/formulas that don't seem to come from homebrew, specifically the  texlive-2013 I just installed via the pkg seems to have landed in usr/local/texlive. Also, I see directories for QT and macGPG2. So my next question is what do I do about these?

I recommend you remove anything in /usr/local to ensure you do not introduce problems for software built using MacPorts. If removing /usr/local reveals that problems were already introduced for software you previously built using MacPorts, rebuild those MacPorts ports, for example using rev-upgrade as suggested earlier in this thread.

> Can they coexist/be installed with macports? If not, should I move to homebrew, except I have quite a bit installed via macports, and would ahve to install all these via homebrew, correct??

As a manager of the MacPorts project, and having not used any other OS X package manager in many many years, I of course recommend you use MacPorts. If there’s anything Homebrew is doing for you that MacPorts isn’t, please let us know so that we can investigate whether we can improve MacPorts to meet your needs. For example, if individual software packages you need are not in MacPorts, file port request tickets in our issue tracker.
