Sanity check causes problems with our setup

[ocaisa]

At JSC we have the current modules environment which contains some modules that conflict with EB. To avoid any problems I created the following module file that changes the module path to only point to the EB space:

#%Module1.0##########################################################
##
## EasyBuild ZAM Developers modulefile
##
proc ModulesHelp { } {
  puts stderr "  This module will purge the default module environment and replace it "
  puts stderr "  with the EasyBuild module environment instead."
  puts stderr "  I have installed toolchains for GCC and Intel compilers by default."
  puts stderr "  For the Intel compiler toolchain with Parastation MPI, load the impmkl module"
  puts stderr "  - this includes Intel MKL using Parastation MPI"
  puts stderr "  For the Intel compiler toolchain with Intel MPI, load the ictce module"
  puts stderr "  - this includes Intel MKL using Intel MPI"
  puts stderr "  For the GCC compiler toolchain with Parastation MPI, load the gmpolf module"
  puts stderr "  - this includes Parastation MPI, OpenBLAS, FFTW and ScaLAPACK"
  puts stderr "  "
}

module-whatis   "Module to set up ZAM developer space for EasyBuild"


# Set the default path to be the common development space
set            pkgroot           /usr/local/eb      
setenv         EASYBUILD_PREFIX  $pkgroot

# Make sure that people build in a unique space so we avoid stepping on each others toes as much as possible
setenv         EASYBUILD_BUILDPATH   "/tmp/$::env(USER)"

# Indicate that we (currently) use Tcl modules 
setenv         EASYBUILD_MODULES_TOOL   EnvironmentModulesTcl

# Set the python path to find all the EasyBuild files
prepend-path     PYTHONPATH       $pkgroot/lib/python2.6/site-packages

# Set the path to find the eb command AND to find the modulecmd.tcl
prepend-path     PATH         $pkgroot/bin
prepend-path     PATH         /usr/local/module

# Finally, purge installed modules and set the new module path
module purge
setenv      MODULEPATH  /usr/local/eb/modules/all 

The problem is loading this module leaves you with a loaded module that needs to be found in the module path. I created a dummy module (which is identical except for the last 2 lines) for this case that, when unloaded, puts you back into the default environment:

# Finally, ~~purge installed modules and set the new module path~~ sneakily reset the path
unsetenv        MODULEPATH  /usr/local/modulefiles/COMPILER:/usr/local/modulefiles/MATH:/usr/local/modulefiles/SCIENTIFIC:/usr/local/modulefiles/IO:/usr/local/modulefiles/TOOLS:/usr/local/modulefiles/MISC

The problem is that this approach breaks the sanity checks. Is there a better way?
