And the third version.
I added a note about the possible circular RDEPEND issue. I wanted to
do that through a footnote but wasn't able to get it working so it's
a standard bracket now).
I separated pkg_config (as the circular RDEP issue shouldn't apply
there) and added PDEPEND as well.

There are three classes of dependencies supported by ebuilds:
\begin{compactitem}
-\item Build dependencies (\t{DEPEND}). These must be installed and usable before the ebuild
- is installed.
-\item Runtime dependencies (\t{RDEPEND}). These must be installed and usable before the ebuild
- is treated as usable.
-\item Post dependencies (\t{PDEPEND}). These must be installed at some point.
+\item Build dependencies (\t{DEPEND}). These must be installed and usable before any of
+ the ebuild \t{src\_*} phase functions is executed. These may not be installed at all
+ if a binary package is being merged.
+\item Runtime dependencies (\t{RDEPEND}). These must be installed and usable before
+ the results of an ebuild merging are treated as usable.
+\item Post dependencies (\t{PDEPEND}). These must be installed at some point before
+ the package manager finishes the batch of installs.
\end{compactitem}
+Table~\ref{tab:phase-function-dependency-classes} lists dependencies which must be satisfied before a particular phase function is executed.
+
In addition, \t{SRC\_URI}, \t{HOMEPAGE}, \t{PROVIDE}, \t{RESTRICT}, \t{PROPERTIES}, \t{LICENSE} and
\t{REQUIRED\_USE} use dependency-style specifications to specify their values.
