Found it! :-> When I built perl 5.8.0 (by hand, not CPAN) I didn't find an easy way to let it be automatically installed as perl-5.8.0 (I'm sure there is one, but I couldn't work it out). So, I let it build & install as 'perl', and then changed the name to include the version, restoring the 'perl' as a link to my previuos version.
The problem was in the Config.pm that the new install built - it contained 2 references to '/usr/local/bin/perl', under the names 'perl5' and 'perlpath'. Modified these, and make test passed all tests without any trouble. Found this out after running LWP's TEST-script under the debugger, where I saw how Test::Harness read data from Config.pm. Thanks for all the suggestions, I was really confused for a while! :-> /Mattias
