I do agree completely. inter-library dependencies would be the Right
Thing[pm]. But I suspect it won't be easy to convince the Debian perl
maintainers to change their core package ... I might be wrong though.
Who wants to file the bug?

On the other hand, I would like to have an acceptable workaround to
promote FreeRADIUS with working rlm_perl for Debian.

Hmm ...

That could be a starting point ...
