     Type:  enhancement           |     Status:  new
 Priority:  Normal                |  Milestone:
Component:  base                  |    Version:  2.3.4
 Keywords:  uninstall dependents  |       Port:
----------------------------------+--------------------------------
 When an uninstall command fails because of dependents, the user is
 prompted to uninstall the dependents first:

 {{{
 # port uninstall gimp2 @2.8.2_2+help_browser+python27
 --->  Unable to uninstall gimp2 @2.8.2_2+help_browser+python27, the
 following ports depend on it:
 --->    gimp-app @2.8.0_0
 --->    gimp-app @2.8.2_0
 --->    gimp-gap @2.6.0_5
 --->    gimp-jp2 @2.2.0_4
 --->    gimp-jp2 @2.2.0_5
 --->    gimp-lqr-plugin @0.7.1_1
 --->    gutenprint @5.2.7_0
 --->    gutenprint @5.2.7_1
 --->    icns-gimp @0.1_1
 --->    ufraw @0.18_2
 --->    xsane @0.998_0
 --->    xsane @0.998_1
 Error: org.macports.uninstall for port gimp2 returned: Please uninstall
 the ports that depend on gimp2 first.
 }}}

 When this error is triggered, could the feedback add,

 {{{
 Please uninstall the ports that depend on gimp2 first, or use uninstall
 --follow-dependents
 }}}

 You wrote the code, tell people about it, make everybody happy.

 Cheers,
 Dave
