Perl 5.9.4 and (hopefuly soon) 5.8.9 will support "relocatable perl" -- meaning that paths to @INC can be set at compile time to be relative to the perl binary instead of hard-coded. The key to making this work reliably appears to be having $^X be an absolute path to the perl binary, which may or may not be true on all platforms and in all situations.

This is an important feature for Vanilla Perl and possibly for others as well, so I'm looking for a quick poll of monks: Is your $^X an absolute path?

It seems to be for me on both linux and win32 -- but I'm looking for results on unusual/old systems (particularly older win32 operating systems) or perls running in some embedded or unusual fashion (e.g. mod_perl, win32 services, etc.).

A tip of the hat, fame and fortune, or at least a ++ vote awaits anyone that can find a situation where $^X isn't absolute.
