Hello I am somewhat new to Linux and very new to PERL. I am also receiving the same message as post +ed above. I tried using this command as mentioned above but it still fails. I am running Debian Linux sarge. perl -MCPAN -e shell CPAN> o conf make /usr/bin/make I got into this whole mess by trying to install NET::SSH:Perl. This has been a nightmare. Checking if your kit is complete...
