grunt-rpm broken on OSX (w/ working command-line example)

[asnowfix]

This is the same problem than the one recently fixed by sbt/sbt-native-packager#22, invoking the rpmbuild command-line, but from scala (instead of from Node+Grunt).

[...]
Spawning rpmbuild: {"cmd":"rpmbuild","args":["-bb","--target","noarch","--buildroot","/Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild/tmp","/Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild/SPECS/mpf-client.spec"]}
Warning: error: Unable to open temp file.
    Unable to open temp file. Use --force to continue.

Aborted due to warnings.

Here is the spawned command-line execution job:

$ rpmbuild -vvv -bb --target noarch --buildroot /Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild/t

RPM build errors:
    Unable to open temp file.

Once the generated command is changed into the following format, it works fine:

$ rpmbuild -vvv -bb --target noarch --buildroot /Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild/t
mp --define "_topdir /Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild" --define "_tmppath /tmp" /Users/kowalskif/Desktop/GIT/hp-ws/mpf-client/_rpmbuild/SPECS/mpf-cli
ent.spec

As a confirmation, here is the content generated rpm:

$ rpm -qlp _rpmbuild/RPMS/noarch/mpf-client-0.1.0-SNAPSHOT20140616220711.noarch.rpm 
/export/u1/pos-static/mpf/lib/bower_components/angular/angular-csp.css
/export/u1/pos-static/mpf/lib/bower_components/angular/angular.js
/export/u1/pos-static/mpf/lib/bower_components/angular/angular.min.js
[...]

By default, rpm use /var/tmp as tmppath. Have you tried to override this value in rpmrc file ? (Either in /etc/rpm/rc or ~/.rpmrc). For more infomration, see tmppath setup in rpmrc

[asnowfix]

@dod38fr yes, and the work-around work, but this should not be required on OSX, an OS whose built-in packaging system is not RPM & therefore where there is no /etc/rpmrc or ~/.rpmrc by default.
