I checked my path and current directory to be sure I wasn't looking somewhere I didn't mean to be: $ echo $PATH

/bin:/usr/bin:/sbin:/usr/sbin:/usr/5bin:/adm/bin:/opt/admin/bin:/usr/local/bin:/usr/ccs/bin:/usr/ucb:/opt/VRTS/bin $ $ ls usr/* ls: usr/*: No such file or directory $

Thanks for your time looking...

    IIRC, we used to see something exactly similar (:-D) to this in a previous incarnation when attempting to run perl v5.10 against libraries (badly) pre-built and and installed for v5.8.

    Are you sure that you haven't got a similar situation whereby there's a mismatch between the perl version you're running and the version for/from which the library/ies were built and installed ?

    perl -V might well be of use since, amongst other things, it identifies the library locations perl is attempting to read.

    Just a thought ...

    A user level that continues to overstate my experience :-))

      I'm happy for anybody else's thoughts since mine don't seem to be liking me much at the moment ;)

      When this all started I did have to install WWW:Mechanize in order to get the ball rolling. I don't recall any errors at the end of it but that may have been because I was figuring that it'd just magically work afterwards...

        I think all of this comes down to a botched install of LWP::UserAgent, which should include LWP::Protocol::http. Maybe explicitly installing LWP::Protocol or LWP::Protocol::http can get the situation unstuck, but I wonder how the other modules can pass their test suites when the most basic prerequisites are missing.

        Maybe you are mixing two versions of Perl, and have half of the module installed on one version and half on the other? Mixing Perl module directories seems like it's always a recipe for bad interactions to me...
