On top of WWW::Mechanize I want to install WWW::Mechanize::Frames. So I downloaded the tarball, unpacked it and ran

perl Makefile.PL
make
make test
make install
[download]

The first three steps looked all right. Unfortunately, the fourth step one did not ...

My understanding of the error message is that something is wrong with line 557 of Install.pm.

my(%from_to) = %$from_to;

This line is part of the subroutine install which is flagged as #XXX OS-SPECIFIC.

Suggestions on this issue are greatly appreciated - Thank you!

Kind regards
