Subject: Re: [MTT users] question on MTT setup instructions.

Hi Jennis,

FWIW, I run MTT using an MTT source code checkout. (This is
admittedly not the Right Way to distribute software, but it
works.) Try this:

  $ svn checkout
  $ cd ompi-core-testers
  $ client/mtt --file samples/ompi-core-template.ini --verbose

What's the URL for this page?

LIB is where you want to put the supporting perl libraries.
PREFIX is where you want to put the mtt executables (which
are perl scripts).

Yes, PERLLIB (and also PERL5LIB) is an env var. You only
need it if, e.g., a certain perl module needed by MTT is in
a non-standard location. E.g., if you get errors like the
below, you will need to set PERLLIB (and PERL5LIB) to the
location of the missing module:

  Can't locate in @INC (@INC contains: /ws/ompi-tools/perl/lib/sun4-solaris-64int /ws/ompi-tools/perl/lib /ws/ompi-tools/perl/lib/usr/perl5/site_perl/5.8.4/sun4-solaris-64int /usr/perl5/5.8.4/lib/sun4-solaris-64int /usr/perl5/5.8.4/lib /usr/perl5/site_perl/5.8.4/sun4-solaris-64int /usr/perl5/site_perl/5.8.4 /usr/perl5/site_perl /usr/perl5/vendor_perl/5.8.4/sun4-solaris-64int /usr/perl5/vendor_perl/5.8.4 /usr/perl5/vendor_perl .) at -e line 1.
  BEGIN failed--compilation aborted at -e line 1.

Let me know if you get something like the above (in some odd
perl installations LWP::UserAgent won't be found).
