qdepends(1)qdependsqdepends(1)NAMEqdepends - show dependency info
SYNOPSISqdepends <opts> <pkgname>
DESCRIPTION
The qdepends applet has a couple different modes. Normally it is
geared towards answering the queries "what does package X depend on"
and "what packages depend on X". Both can further be classified into
build, run, and post dependencies.
By default, it will tell you the build time dependencies only (DEPEND).
Currently, qdepends will only query installed packages. There is no
support for querying packages not yet installed (the equery(1) tool can
do that).
If there is no answer to your query (i.e. you've asked for a package
that is not installed, or a version that does not match), then you will
get back no output.

EXAMPLES
For finding out what a particular package depends on for building, you
could do:
$ qdepends nano
app-editors/nano-2.3.2: >=sys-libs/ncurses-5.9-r1[unicode] sys-apps/file ...
This tells us that we have app-editors/nano-2.3.2 installed and it
depends on ncurses (among other things).
