 Priority:  Normal           |   Milestone:                                   
Component:  ports            |     Version:  1.5.0                            
 Keywords:  parsing variant  |  
-----------------------------+----------------------------------------------
 if you attempt to clean all uninstalled ports using the command 'port
 clean --archive uninstalled' you will receive the error:

 Error: Error executing darwin_7: nesteedsums is not supported on Panther
 (OS X 10.3.x).
 Error: Unable to open port: Error evaluating variant

 This is one example, many ports (for example GiNaC and cln) also have this
 problem. It is unclear why this error is occurring on my system as it is
 running 10.4, but clearly the ability to clean the port should not be
 dependent on the platform or variants and it is unclear why this parsing
 problem is occurring in the first place.
