Most perl modules can be installed with the following commands:
# the following will open a shell-like perl interface
perl -MCPAN -e shell
# it may ask questions, see below
install IO::Socket::SSL
install Crypt::SSLeay
then the modules will be autofetched from the Internet, compiled and installed.
if perl should ask questions after executing "perl -MCPAN -e shell", just always take the default setting. only once you explicitly you have to select a mirror to download from. just set anything there. if the mirror does not work afterwards, you can reset it to the main download site by executing the following commands on the perl shell:
o conf urllist set
ftp://ftp.perl.org/pub/CPAN/
o conf commit
