Re: Perl install problems OSX 10.4.11

Hi,

Thank you for the very informative response Alan.

I think the problem is probably to do with my Perl install. I looked  
in /System/Library/Perl/
but the Perl folder contained 5.8.6 not 5.8.8. I could not find any  
of the following:
Fcntl
HTML
HTTP
LWP

I previously installed some applications using MacPorts, and it  
appears that there is an
install of Perl 5.8.8 in /opt/local/bin/.

Over the weekend still trying to solve the problem I also installed  
Perl 5.10.1 in an attempt
to upgrade my system Perl install. That is in /usr/local/bin/.

I also searched /usr/local/lib/perl5/5.10.1/ and /opt/local/lib/ 
perl5/5.8.8/ and it would appear
that the MacPorts install is the most complete but I could not find  
an LWP directory or HTTP,
and I was not sure where to look for URI. The HTML directory  
contained entities.pm, and
headerParser.pm but no Cookies

Is it possible to upgrade the system Perl install to a full version  
of Perl 5.8.8?

Thanks,

Terrence
