I have not had any problems with straight Requires.  Yum seems to always
handle straight requires correctly properly by, 
first it installs any required packages
then it installs the package it's self. 

if in [core] / devel / gnu-crypto / gnu-crypto.spec

why not replace the 

Requires(post):   java-gcj-compat >= 1.0.31
Requires(postun): java-gcj-compat >= 1.0.31

with 

Requires: java-gcj-compat >= 1.0.31.

The post and postun problems I am having seem to be because
 /usr/bin/rebuild-gcj-db can not be found during post and postun.  If
Requires: java-gcj-compat >= 1.0.31 is used, whenever
 the post or postun is taking place, rebuild-gcj-db will be present.
