 Reporter:  ryandesign@…  |      Owner:  michaelld@…
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.2.1
 Keywords:                |       Port:  qt4-mac-mysql55-plugin
--------------------------+------------------------------------
 Oddly, although qt4-mac-mysql55-plugin and its subports declare conflicts
 with one another:

 {{{
 $ port info qt4-mac-mariadb-plugin
 qt4-mac-mariadb-plugin @4.8.5 (aqua, databases)
 Variants:             debug, (+)universal

 Description:          Qt MySQL database plugin for mariadb
 Homepage:             http://qt.nokia.com/

 Build Dependencies:   pkgconfig
 Library Dependencies: qt4-mac, mariadb
 Conflicts with:       qt4-mac-mysql5-plugin, qt4-mac-mysql51-plugin, qt4

 }}}
 {{{
 $ port installed qt4-mac-mysql5-plugin
 The following ports are currently installed:
   qt4-mac-mysql5-plugin @4.8.5_0 (active)
 }}}


 MacPorts doesn't seem to recognize this, and allows me to install another
 subport anyway, without letting me know beforehand that there will be an
 activation conflict:
