in mandriva, we needed:

# rpm 4.4.6 killed SOURCEPACKAGE, but this was announce lately, and will
# break all older tools that was using it (mdv 2006, 2005) which need this
# tag to know it is possible to rebuild a src.rpm
# This patch readd the tag into src.rpm
Patch88: rpm-4.4.6-SOURCEPACKAGE.patch

which allowed rpm 4.4.2 to handle the .src.rpm created with >=4.4.6
correctly:
