 Hello,

 When I would like to uninstall any package witch has several dependance
 sutch as speex, macport show me an error message  such as  :

 For example with speex.


 {{{
 sudo port uninstall speex
 Password:
 Warning: xcodebuild exists but failed to execute
 --->  Unable to uninstall speex @1.2rc1_0, the following ports depend on
 it:
 --->    ffmpeg @0.7.8_0
 Error: Target org.macports.uninstall returned: Please uninstall the ports
 that depend on speex first.
 }}}
 In my opinion, macport should compute all dependance and show a message
 sutch as :


 {{{
 Below, here is the package dependance.

 Packages list

 If you want verily to uninstall this package, all the dependence will also
 be uninstalled.

 Do you want to continue ?
 }}}

 Note : The dependance is been installed if you install a package bat you
 can't uninstall it or it's very difficult.

 This issus also occured on macport 2.0.3.

 Can you fix this issues  quickly ?

 Best regards

 mparchet
