It's bizarre that it's seg-faulting though. [s]I've never seen make seg-fault.[/s] My original guess was you were missing a dependency for perl 5.14.2 but it has approximately 5, all of which should be included even in an embedded device. And assuming ipkg does dependency resolving, that shouldn't be a problem either.
Actually, it looks like perl might be the culprit here.
./perl -f -Ilib pod/buildtoc --build-toc -q
It seems to actually be using perl to create something else (I want to say perl's documentation but that'd be perldoc, not perltoc).
