Hello,

I am trying to install several modules for Perl so that I can install linblock.pl. I am looking for a linux version of peer guardian 2. I did a search on this site for peer guardian 2 and a poster said that linblock.pl was what to use.

So I decided to try it. I found out that I had to install a few modules before I could install linblock. I was able to install Net::IP, Bundle::CPAN, and LWP::Simple without any problems. When I tried to install IPTables::IPv4 and Signature I got errors. I am not sure how to fix these errors. Below is the errors that I got.

By the way I am running Suse 10.0 Perl version 5.8.7

What happens if you (temporarily) remove the kernel source rpm (or rename /usr/src/linux to /usr/src/_) and try again?

Once I renamed /usr/src/linux to /usr/src/_ the IPTables::IPv4 package was able to compile. However when the script went into the test portion it failed tests and therefore will not install without the use of a force install. I am not familiar with how to force an install. If anyone could help me with that I would appreciate it. This is the command that I have been using to install the IPTables::IPv4 module

perl -MCPAN -e 'install IPTables::IPv4'

How do I modify the command to force the install? Also I am including the tests output so I can hopefully get some input on why its failing to finish installing.

make test had returned bad status, won't install without force
