Ports+: Bug on Package names ― 2007年07月27日 12時37分17秒
Because of this, if package name is specified as a target of gmake, it will try to install multiple versions. In this case, firefox and firefox-devel. Of course, they conflict each other. This target support will likely be removed on next version.
Once upon a time, directory names without categories such as firefox in case of www/firefox were available targets. However, there are some ports in different languages. For example, there are chinese/xpdf, japanese/xpdf, and korean/xpef for graphics/xpdf. This also resulted conflict between different versions. As a result, support was dropped.
Based on these ports+ will probably not support short package names as targets.
