modulefile – module unload is not unsetting environment variables

I have a very simple modulefile:

#%Module1.0#####################################################################
puts stderr "Loading personal environment"
proc ModulesHelp { } {
    puts stderr "tLoads personal environment"
    puts stderr ""
}
setenv MYTEMPVAR sometext

And here is my command line:

> env | grep MYTEMPVAR
> module load ~/wa/example_modulefile
Loading personal environment
> env | grep MYTEMPVAR
MYTEMPVAR=sometext
> module unload ~/wa/example_modulefile
> env | grep MYTEMPVAR
MYTEMPVAR=sometext

According to the modulefile man page unload module command was supposed to turn all setenv’s to unsetenv but it doesn’t seem to be working. Does anyone know what I might be doing wrong here?

For those unfamiliar with modulefiles (they do not seem to be that popular):

• modulefile is a simple bit of code that set or add entries to the PATH, MANPATH, or other environment variables
• modulefiles hide the notion of different types of shells
• modulefiles are written in the Tool Command Language, Tcl and are interpreted by the modulecmd program via the module user interface

This is apparently working as intended: http://sourceforge.net/tracker/?func=detail&aid=2384340&group_id=15538&atid=115538

It seems you are expected to run module unload example_modulefile without giving it the full path to the module file.
