Re^3: Protocol scheme 'http' is not supported

With all the same versions you show above and in your OP, I cannot reproduce your problem. I have a newer version of Perl than you and I'm on a different architecture:

I noticed a discrepancy between versions for HTML::Parser. When you used sudo (above), 3.69 was returned without error:

$ sudo perl -MCPAN -e shell 
...
HTML::Parser is up to date (3.69).
[download]

without sudo (below), 3.55 was returned with an error:

$ perl -MDevel::Modlist -MWWW::Mechanize -e 1
HTML::Parser object version 3.55 does not match bootstrap parameter 3.
+69 ...

This sounds like two separate installations of Perl that are not in sync. I see you've added perl -V output below; what does sudo perl -V produce?

Hi, It does actually look like you have two perls installed. Look at your whereis output, /usr/bin/perl vs /usr/local/bin/perl You can verify this further by doing /usr/bin/perl -V and /usr/local/bin/perl -V I had a similar problem after a release-upgrade on my ubuntu-server. Unfortunately my only solution was to reinstall the system. Best regards, Jimmy	[reply]

Actually, both the /usr/local/bin/perl and the /opt/admin/bin/perl are just softlinks to the actual /usr/bin/perl binary, but thanks for keepin' me honest `$ ls -l /opt/admin/bin/perl /usr/local/bin/perl /usr/bin/perl lrwxrwxrwx 1 root root 13 Apr 10 16:38 /opt/admin/bin/perl -> /usr/ +bin/perl -rwxr-xr-x 2 root root 19208 Dec 16 2011 /usr/bin/perl lrwxrwxrwx 1 root root 13 Apr 27 14:01 /usr/local/bin/perl -> /usr/ +bin/perl` [download]	[reply] [d/l]
