I'm not sure this is 100% a PAR::Packer bug. The logic for determining
the temporary directory is as follows:
- If it's set via an environment variable, that directory is used. (The
PAR::Environment documentation has details on this.)
- If not, it tries to determine the system temp dir from various ENV
vars. In your case this succeeds: /tmp/
- Given a system temp. path, it tries to determine the username.
--> first, it tries getpwuid() if available. (This happens in
myldr/usernamefrompwuid.c for pp'd exes.) I don't know *why* this fails,
but I suspect it's related to the unusual context in which apache runs
CGIs. I lack the expertise to diagnose this.

Would it be possible to set $ENV{USER} as normally done for sessions?
