[SLL] cpan, perl module help

[Mike Bate]

Trying to add a few dependencies to Perl, using CPAN. Here's 
the error from Convert::ASN1,but similar for RDF::Core

$ sudo cpan
cpan> install Convert::ASN1

...
Seems to be ok until the end, when it runs 'make install', 
see below.

Need ideas/help!

...
/usr/bin/make test -- OK

Running make install
mkdir /usr/local/man: File exists at
    /usr/share/perl/5.8/ExtUtils/Install.pm line 112
make: *** [pure_site_install] Error 17
/usr/bin/make install  -- NOT OK
