[scl.org] Question about generating RPMs that depend on SCLs (like python27)

[Alan Robertson]

The key thing here is that it shouldn't be complaining about a 
dependency which is satisfied.  That is, if I have python27 installed 
(which I do), then it should supply python(abi) = 2.7 -- and then RPM 
shouldn't be complaining.

So, either the python27 package doesn't supply that, or the RPM command 
(yum in this case) is broken.  Let's see which...

bash-4.1# *rpm -q --provides python*
Distutils
python(abi) = 2.6
python-abi = 2.6
python-ctypes = 1.0.1
python-hashlib = 20081120
python-sqlite = 2.3.2
python-uuid = 1.31
python-x86_64 = 2.6.6-52.el6
python2 = 2.6.6
python = 2.6.6-52.el6
python(x86-64) = 2.6.6-52.el6

bash-4.1# *rpm -q --provides python27*
python27 = 1-10.el6.centos.alt
python27(x86-64) = 1-10.el6.centos.alt
bash-4.1#

So, the python27 package is broken.  It has an insufficient set of 
"provides".  Significantly insufficient...
