I downloaded Net:

ing and tried it - I got the error about 'No Target to make /usr/lib/perl/5.8/CORE/config.h' - is that the error you got? It's because perl-dev isn't installed on the OS and I haven't included it in the cdevtools pnd. I can probably fix this for the next release, but I'm not convinced you really need it. Here's the thing:
1) You already have Net:

ing on your pandora (in /usr/share/perl/5.8/Net/Ping.pm)
2) There's no C files in the Net:

ing download.
3) Running 'perl Makefile.pl' creates a Makefile, but it's not a C Makefile. They're just using it as a way of copying files. If you got it to work, all 'make install' would do is copy lib/Net/Ping.pm as /usr/share/perl/5.8/Net/Ping.pm (which is already there) and copy some man documentation (which you wouldn't be able to display). You can replicate its behavior by just copying the files yourself.
