[suggest] confusion about alpine (and rf in general)

[Joe Pruett]

the rpms i have installed are alpine-1.10-1.el4.rf and 1.10-1.el5.rf. 
they have a problem with the pine.conf being in /usr/local/lib.  when i 
look at the spec file in svn, it claims to have fixed this problem.  the 
comment for the fix indicates 1.10-2, but the release in the spec is still 
1.

so i am guessing that the spec should have 2.rf as the release?  and that 
leads me to wonder where the el4/el5 is being stuffed in?  there isn't a 
macro in the release field, so is it done on the fly by the build system?
