Just install the crux port from

Download an iso of the latest CRUX release for a precompiled package.
Otherwise, build from the sources in this repository.

(e.g. /usr/ports/contrib/mutt and /usr/ports/local/mutt), the one

Feel free to contact me in case of problems (jw@tks6.net)
Feel free to file a bug report on the Gitea issue tracker:

more information
----------------
See the man pages for prt-get(8), prt-get.conf(5) and prt-cache for more
information. There is also a user manual in the doc directory (as a
tex file). This document should also be available as PDF from

CONSIDER:
- default formats for printf and dup
- add update-footprint, update-md5sum commands (patch in trac)
- add update-footprint, update-signature commands
- sysup
- allow injecting of new (uninstalled) dependencies
- allow to prohibit recompilation of packages when a dependency failed

.B softdeps
if set to yes, during an update operation prt-get will perform a greedy search
of the dependency graph, visiting any \fBinstalled\fP optional dependency of
the ports specified on the command line and recursing until either a leaf node is
found (port that doesn't depend on anything else) or a cycle is created. If a
cycle is \fBnot\fP created by following a soft dependency, then this dependency
relationship is added to the list of edges, and topological sort of the
resulting graph can proceed as usual. The default is \fBsoftdeps no\fP, which
means prt-get will only consider hard dependencies when walking the directed
graph.
