I'll take this for a review.

I hope the correct SRPM url is https://mmorsi.fedorapeople.org/staging/rubygem-compass-import-once-1.0.5-1.fc20.src.rpm , since the one you provided does not work ...

* The .spec differences
  - The .spec file you posted differs from the one included in SRPM. It is just
    small difference in you name in %changelog, so no big deal.

* Update to the latest guidelines
  - The .spec file looks to be generated by old gem2rpm and does not conform
    to the latest Ruby packaging guidelines. Please remove the Requires, which
    are now autogenerated and Provides.

* Test suite is not executed.
  - Please execute the test suite.
  - Although it is not shipped with the gem, it is available upstream [1].

* Move VERSION file into the main package
  - It seems to be runtime dependency. It is read by
    lib/compass/import-once/version.rb

Yes regarding the URL, copy-n-paste err. Updated:

Spec: https://mmorsi.fedorapeople.org/staging/rubygem-compass-import-once.spec
SRPM: https://mmorsi.fedorapeople.org/staging/rubygem-compass-import-once-1.0.5-2.fc20.src.rpm
Koji: http://koji.fedoraproject.org/koji/taskinfo?taskID=7476134

Incorporated feedback. Same note about test suite / minitest5 compatibility as w/ compass-core

Updated

Spec: https://mmorsi.fedorapeople.org/staging/rubygem-compass-import-once.spec
SRPM: https://mmorsi.fedorapeople.org/staging/rubygem-compass-import-once-1.0.5-3.fc20.src.rpm

Unfortunately there is only one test module in this one and it depends on sass-globbing which currently is awaiting a license clarification:

https://github.com/chriseppstein/sass-globbing/issues/24

Shouldn't be a blocker, verified test ran when sass-globbing was installed manually locally, commented test out, will uncomment when that makes it in.

* The spec file differs from SRPM
  - There is BR: rubygem(sass-globbing) enabled in SRPM while disabled in the
    .spec you provided. The latter seems to be what you probably wanted.

* Test suite
  - It seems that 

    sed -i '/sass-globbing/ s/^/#/' test/test_helper.rb
    mv test/fixtures/with_globbing.scss{,.disable}

    Should be enough to execute the test suite without sass-globbing.

* Patching using %patch0 macro
  - I'd suggest to apply the patch using "%patch0 -p1" in %prep section instead
    of the %build section.

Otherwise, the package looks good => APPROVED

Thanks, incorporated all feedback.
