Tying Complex Data Structures using dbmfilters
Perhaps DBM::Deep is the module you're looking for since it describes itself as A pure perl multi-level hash/array DBM, and rather conveniently has a tie interface.
DBM::Deep is pure-Perl, so installation issues do not apply. You just need to copy the source somewhere accessible.
