MrSnrub has asked for the wisdom of the Perl Monks concerning the following question:

Hello! I am trying to install XML::Parser, and I understand that before I do that I have to install expat. I launch a Terminal window and type "sudo port install expat" and that gives the following output:

---> Fetching archive for expat ---> Attempting to fetch expat-2.0.1_1.darwin_10.x86_64.tbz2 from http://packages.macports.org/expat ---> Fetching expat ---> Attempting to fetch expat-2.0.1.tar.gz from http://ykf.ca.distfiles.macports.org...istfiles/expat ---> Verifying checksum(s) for expat ---> Extracting expat ---> Configuring expat ---> Building expat ---> Staging expat into destroot ---> Installing expat @2.0.1_1 ---> Activating expat @2.0.1_1 ---> Cleaning expat

I then type "port installed" and "expat @2.0.1_1 (active)" appears. So far so good. I then try to install XML::Parser. I downloaded XML- Parser-2.41.tar.gz. I cd to my Downloads folder and type in "gzip -d XML-Parser-2.41.tar.gz" and "tar xvf XML-Parser-2.41.tar.gz" and that creates a directory called XML-Parser-2.41. I cd to that directory and type "perl Makefile.pl" and I receive the following error message:

Expat must be installed prior to building XML::Parser and I can't find it in the standard library directories. Install 'expat-devel' package with your OS package manager. See 'README'.

I try to install expat-devel by typing in "sudo port install expat- devel" but that gives an error message "Error: Port expat-devel not found." I am completely at a loss here. Where am I going wrong? Is expat still not completely installed? Is there some additional configuring I need to do before moving on to the XML::Parser step?
