I kinda fail to see how it relates to building packages, but this'll 
give you the "what would break if I removed foo" answer without actually 
ever doing anything:
$ rpm -e --test <package>

Eg.

[pmatilai at localhost ~]$ rpm -e --test python-magic
error: Failed dependencies:
	python-magic is needed by (installed) rpmlint-1.0-2.fc14.noarch
