[Dovecot] rebuilding dovecot 1.0 beta7 at.src.rpm mysql error

[dave]

hi all

i'm trying to rebuild the 1.0 beta 7 src rpm from atrpms.net to use 
mysql 5, instead of mysql 4

but i'm having issues when it gets to the mysql part of the make

i have mysql 5 installed (via mysql.com rpm's)

i changed the spec file where it says Buildrequires
to say MySQL-devel (instead of mysql-devel)

but it always comes back with this error, and i don't know what it 
means, i also tried leaving it as mysql-devel, but still get the same error

when i run
rpmbuild -ba dovecot.spec && rpm -Uvh --force ../RPMS/i386/dovecot*

am i doing this completely wrong, is there something else i need to do 
to be able to use mysql 5?
