For example if Perl does not have the appropriate read/execute permissions, it will not add the directories.

You will have to collect more data on the situations when @INC gets populated and when not. Maybe you are using different Perl interpreters?

Also, some code and a ls -lR of the relevant directory could be helpful. These directories are not network mounted or on otherwise removable devices, are they?
