[Modules] envars not unset when unloading

[Roger M. <rm...@mu...>]

Hello,

When unloading this modulefile the envars it sets are not unset:

#%Module1.0#####################################################################
##
## GCC modulefile
##
proc ModulesHelp { } {
        global version

        puts stderr "\tSets up environment for GCC v$version."
}

module-whatis   "sets up environment for GCC v13.3.0"

# for Tcl script use only
set     version 13.3.0
set     root    /usr/local

conflict gcc

if { [ module-info mode load] } {
    prepend-path	INFOPATH	$root/share/info
    setenv      	LD_LIBRARY_PATH	$root/gcc13
    prepend-path	MANPATH		$root/share/man
    prepend-path	PATH		$root/bin/
    setenv          GCC                 $root/bin/gcc13
    file link -symbolic /home/rmason/bin/gcc $root/bin/gcc13
    file link -symbolic /home/rmason/bin/g++ $root/bin/g++13;
    file link -symbolic /home/rmason/bin/gfortran $root/bin/gfortran13;
}

if { [ module-info mode ] == "unload" || [ module-info mode ] == "remove" } {
    exec rm /home/rmason/bin/gcc;      # 
    exec rm /home/rmason/bin/g++;      # 
    exec rm /home/rmason/bin/gfortran; # 
}

I am running version modules-5.6.0 installed on FreeBSD-13.5 using the
