Yes - this is most likely something we've seen before happening with
Apples perl on Snow Leopard. We're still trying to convince Apple that
this is a bug, but this proves slightly tricky.

I _think_ we have a workaround, that I wanted to test before sending a
reply. But funnily enough, another user reports the same problem it
seems just this morning. So if you're up to some testing yourself:

  1. install a different Perl distribution. The easiests would be
     ActivePerl from

       http://www.activestate.com/activeperl/downloads

     This should install a new perl distribution into
     /usr/local/ActivePerl-5.12.

  2. if you are still installing SHARP/autoSHARP: start again using
     the command

     a) if you are using sh/bash/ksh/zsh:

        BDG_perl=/usr/local/ActivePerl-5.12/bin/perl
        export BDG_perl
        ./GPhL_SHARP_production-academic_install.sh

     b) for tcsh/csh

        setenv BDG_perl /usr/local/ActivePerl-5.12/bin/perl
        ./GPhL_SHARP_production-academic_install.sh

  3. if you have already an installation: modify all

       machines/*/host.setup

     files (there should be only one) so that the BDG_perl parameter
     in there points to

       /usr/local/ActivePerl-5.12/bin/perl

As I said, I haven't tested this (yet) in the context of a
SHARP/autoSHARP server ... but it sounds right. If you try this and it
works (even after loggin out again), please let us know.

If it doesn't work I'm sure you'll let us know anyway ;-)

Cheers

Clemens
