mysql5 vs mysql devel

[Payam Minoofar]

Hi,

When I try to build Amarok, port hits this barrier, which doesn't seem to make sense:

[payam-imac:~] payam% sudo port install amarok +universal
Password:
Portfile changed since last build; discarding previous state.
--->  Computing dependencies for amarokError: Unable to execute port: Can't install mysql5 because conflicting ports are installed: mysql5-devel


Is there a way to make port to be able to compare these two versions reported for the two versions of mysql5?
[payam-imac:~] payam% port info mysql5-devel
mysql5-devel @5.5.0-m2 (databases)

vs.

[payam-imac:~] payam% port info mysql5
mysql5 @5.1.41 (databases)


Is the "m2" in the devel version throwing it off?
