[Solved?] Installing multiple versions of Firefox at the same time

Question

I would like to install the normal Firefox in the repositories and also firefox-pgo-minefield-smp from the AUR so that I may use either one as desired. 
Looking at the current PKGBUILD from http://aur.archlinux.org/packages.php?ID=33506 (pkgbuild @ http://aur.archlinux.org/packages/firef … p/PKGBUILD ) I am thinking that perhaps I would modify this line:
export LDFLAGS="-Wl,-rpath,/usr/lib/firefox-$_prever -Wl,-O1,--sort-common,--hash-style=gnu,--as-needed"
to reflect the path where I would like to install it like so:
export LDFLAGS="-Wl,-rpath,/opt/firefox-$_prever -Wl,-O1,--sort-common,--hash-style=gnu,--as-needed"
And then presumably fix my symlink at /usr/bin/firefox to point back to /usr/lib/firefox-2.6 again. (and also fix the menu links and I realize I would have to use an ugly 'pacman -U tarball --force' to install it -- there's got to be a better way as that is very ugly and wrong surely???? Perhaps modify the pkgname as well as conflicts and provides so I could install it more normally?)
Correct?  Would I also need to modify a prefix or such besides this and if so where in the pkgbuild (ideally) or source would you recommend (must I change the actual makefile or does my modification in the PKGBUILD take care of this?  Would you in your experience recommend another approach for this?
I thought it wise to ask here before hacking away with this stuff and possibly hosing my system in unforeseen ways.   Please forgive my greenness.  I have spent a few hours researching this but still am not quite sure thus I ask. While I think I could do it with a straight compile with a modified configure I'm unsure of how to do it best using the arch tools...
Thanks for your time.

Answer 1

Basically solved but not yet mastered.
So I've figured out how to do this, it works, but not yet optimally and I am unsure about some things.  Namely:

It seems as though it is a bit messy, as if I have more than I need installed. Especially the two entries in /opt/lib/.  Do I really need all this?

^ A dirty hack to download the latest nightly of the electrolysis tree, pgo optimized for an intel i686 P4 (not native to get around the seg fault bug). I just commented out the .desktop files as well as the icon for now. Also the conflicts and provides section have merely been commented out. The goal is to have this work independently from the standard firefox allowing me to run both on the system at the same time.
Anyone see anything that I have missed and could fix as far as doing the separate install in /opt using makepkg and the pkgbuild?   I've been using arch less than a month and this is the first I've really hacked with a PKGBUILD and mozconfig so I feel I could really use the help. Any insight appreciated greatly.
