Change fedora template for range of dependencies

[fedorkk]

It's a decision for #94

[fedorkk]

There is a problem with String prepend method. Travis environment configured with ruby 1.8.7. Is it necessary to use so old ruby version? It's expired since 2014.

Thx for the PR. I'll take look later ...

Is it necessary to use so old ruby version?

Well, yes ... gem2rpm is still available in EPEL6.

[fedorkk]

Ok, I fixed it for 1.8.7. Thre is one more problem with undefined minitest, but I don't know how I could break it.

@voxik what's the status of this?

What I really don't like is the change in the template. As I already mentioned in #94, the BRs should not be versioned. The dependencies does not matters, the only thing which matters is if the test suite is passing. Even if we figure out that the test suite is not passing, because BR was updated in Fedora, then again, restricting the BR does not fix the issue itself. And the opposite way, that the package becomes FTBFS just because the BR version is very restricted is also not tempting (although we could ask upstream to relax the dependency if we discovered the library is compatible with newer version).

IOW I'm fine accepting the PR without changing the default template, because the with is useful in itself, but I don't want to change the template.

I've been asked to make this PR in the Russian fedora community, but it was three years ago and I don't remember, what happens here. I can change the PR, but could you please describe more detailed, what would you prefer to have?

And is it really make sense to create rpm packages from gems? Almost all ruby developers use version control systems like rbenv and manage gems with bundler. It allows us to have different ruby versions with different gems for each project on one machine.
