Good catch. To me this looks like a bug in Leopard's /bin/ps: When the
"-a" flag is present, it ignores the "-p pid" flag. I have immediately
filed a bug with Apple's bugreporter.

The environment variables (in particular $HOME and $USER) with which the
installer runs the postflight script keep changing between OS releases,
sometimes between minor releases. There was a time when the current
version of postflight did the right thing, but on Leopard your
suggestion is looks correct, and it looks correct for Tiger, too.
However, I think this needs some more testing: When I try to execute
this by hand from a root command line prompt, I get weird error messages
(perhaps due to my using tcsh as login shell):
root# sudo -i -u costabel /sw/bin/pathsetup.sh
Badly placed ()'s.
With another command it gets weirder:
root# sudo -i -u costabel /usr/bin/printenv HOME
\312\376\272\276^B^G^C^PEp^L^R: Command not found.
^QU\211\345WVS\203\354,\213u^H\213]^L\353^E\350\261\377\377\377\307D:
Event not found.
There is definitely something fishy about this "-i" flag when used with
a command. On the other hand, "-H" seems to work correctly:
root# sudo -H -u costabel /usr/bin/printenv HOME
/Users/costabel
root# sudo -H -u costabel /sw/bin/pathsetup.sh

Your environment seems to be correctly
set up for Fink already.
