I don't know what spectool is, but I can demonstrate what I see every
time I work with this package:

[tgl at rh3 ~]$ cd f-pkg/python-psycopg2/master/
[tgl at rh3 master]$ ls
psycopg2-2.4.4.tar.gz  python-psycopg2.spec  sources
[tgl at rh3 master]$ fedpkg srpm
sh: python3: command not found
error: Macro %py3ver has empty body
sh: python3: command not found
error: Macro %py3ver has empty body

sh: python3: command not found
error: Macro %py3ver has empty body
Wrote: /home/tgl/f-pkg/python-psycopg2/master/python-psycopg2-2.4.4-1.fc18.src.rpm

The generated SRPM is fine, and I can (and do) test it in mock, but
those messages would certainly scare anybody not familiar with the
package.  I've seen similar behavior with other packages.  I'd like
this guideline to show how this sort of thing can be avoided.
