<entry>The port requires a specific version of

can be specified with value such as

<entry>The port requires GCC (<command>gcc</command> or
<command>g++</command>) to build. Some ports need any
GCC version, some require modern, recent versions. It
is typically set to <literal>any</literal> (in this
case, GCC from base would be used on versions of &os;
that still have it, or <literal>lang/gcc</literal> port
would be installed when default C/C++ compiler is Clang);
or <literal>yes</literal> (means always use stable, modern
GCC from <literal>lang/gcc</literal> port). The exact
version can be also specified, with a value such as
<literal>4.7</literal>. The minimal required
version can be specified as <literal>4.6+</literal>.
The GCC from the base system is used when it satisfies
the requested version, otherwise an appropriate compiler
in built from the port, and the <makevar>CC</makevar>
and <makevar>CXX</makevar> variables are adjusted
accordingly.</entry>
