Summary: Failures when more than one default

Initial Comment:
Hi,

I've been messing around with switcher scripts for some
of the locally
installed software on our cluster to allow our users to
choose between
different versions of our applications. I've written a
modulefile for
them and installed them via:

        switcher prog --add-name version /path/to/program

The modulefile is copied to /opt/env-switcher/share and
shows up
correctly when I do:
        switcher
and
        switcher prog

Additionally, I can use the 'module' command to load
and unload the
modules, and the environment is updated appropriately.

The problem comes when I use switcher prog =
prog-version --system

Then every new shell invocation gives:

mpi(70):ERROR:105: Unable to locate a modulefile for
'mpi/lam-6.5.9 ****
prog/prog-version'

If I remove the default entry from mpi with:
        switcher mpi = none --system

then I don't get the errors.

In summary:
        -I've created a new modulefile
        -I can load/unload it fine using the module command
        -Switcher if it's the _only_ module with a
default attr
        -If there is more than one tag with a default
attribute it fails.

I believe the failure occurs in
/opt/modules/oscar-modules/switcher/1.0.9, near the end
in the section:


set modules_to_load [exec switcher --show-exec]
  if { $modules_to_load != "" } {
      module load $modules_to_load
      #module load "[exec switcher --show-exec]"
  }


Unfortunately I don't really know tcl. Any ideas?
