Is it ok to omit some BuildRequires?

[Achilleas Pipinellis]

Hey guys,

There are some gems that in order to run their test suite, they require 
some other gems that are not yet packaged. For example see here [0] the 
orm_adapter, where I have commented what we are missing.

I have seen this behaviour and with some other rubygem packages on gitweb.

Is it ok to omit some BuildRequires and to what degree is that tolerable?

Thanks
