15.2.8 - Incomplete package installation or removal
In some odd cases, you may find that a package was not added or deleted completely, because of 
conflicts with other files. The incomplete installation is usually marked with "partial-" prepended to the 
package name. This can, for instance, happen when you coincidentally press CTRL+C during 
installation: 
$ sudo pkg_add screen-4.0.3p1
screen-4.0.3p1:

As mentioned in the introduction, packages are compiled from the ports tree. In this section we will

IMPORTANT NOTE: The ports tree is meant for advanced users. Everyone is encouraged to use the 
pre-compiled binary 
packages
. Do NOT ask beginner questions on the mailing lists like "How can I 
get the ports tree working?". If you have questions about the ports tree, it is assumed that you have read
