Well, with apbs, it just did :) (I switched it to /bin/bash for good
measure).
I think switching the second and third lines (setting the $PATH first)
would probably be better. I assume source %p/bin/init.sh is doing the
right thing as it sets VERSIONER_PERL_PREFER_32_BIT to yes.

If the user has any instance of
typeset -U path
then only the original entry is preserved, as shown in this example.
I've contrived it by putting /sw/bin and /sw/sbin at the end to begin
with, and then I just print the first five elements of the path array
for clarity:
sage-% print $path[1,5]
/usr/local/phenix-1.4-4/build/mac-intel-osx/bin /usr/bin /bin /usr/
sbin /sbin
sage-% source /sw/bin/init.sh
sage-% print $path[1,5]
/usr/local/phenix-1.4-4/build/mac-intel-osx/bin /usr/bin /bin /usr/
sbin /sbin
Now reset the $PATH and $path:
sage-% PATH=/usr/bin:/bin
sage-% print $path[1,5]
/usr/bin /bin
sage-% source /sw/bin/init.sh
sage-% print $path[1,5]
/sw/bin /sw/sbin /usr/bin /bin /usr/X11R6/bin
