Hi Fabricio, I have also run into this problem when building
modules-based rpms when the user shell is zsh or (sadly) tcsh.

I think the reason why the module command works when your shell is bash
is because bash is the only shell that supports exporting shell
functions (export -f). In all other shells, the module command is a
shell function or alias, but can't be exported through the environment
to subshells. Since /etc/profile.d/modules.sh is only loaded in
interactive shells, it isn't loaded by the rpm build shell scriptlets
for example.

The only solution I've found is to start an interactive bash shell
before rpmbuild, or source the file as you've done.

HTH,
