Why?

portage substitutes "" when metadata keys are unset during depends 
export.  Seems kind of pointless requiring an empty var- yes it could 
be used for typo checks where the dev does a 

HOMEPAGe="blah"

but no other var has an actual check of that sort- to do the check 
would require mangling ebuild.sh also, which I think is kind of daft.

Repoman complains if the var is unset/empty, works for me personally.
