Inactive/Uninstalled confusion

[Romain]

Hello list,

I've come across a strange behaviour in DarwinPorts (1.3.2), that I  
thought I'd read would be corrected in MacPorts (1.4). Well,  
apparently not. I've just upgraded and it's still there.

The problem is that MacPorts sometimes thinks old versions of an  
active port are still installed, and sometimes not. Confusing to say  
the least. Example :

bagheera:~ smokey$ sudo port location atk
The following versions of atk are currently installed:
         atk 1.12.2_0
         atk 1.12.4_0
         atk 1.18.0_0 (active)
Error: port location failed: Registry error: Please specify the full  
version as recorded in the port registry.
bagheera:~ smokey$ sudo port uninstall atk-1.12.2_0
Error: port uninstall failed: Registry error: atk-1.12.2_0 not  
registered as installed.
bagheera:~ smokey$

So it seems that the port is indeed uninstalled, but for some reason  
MP remembers it as installed but inactive.

Is anyone else experiencing this ? If so, it might be a cause for a  
neat bug report.

Cheers,

Romain
