perl version for usage in paths is extracted from variable \Envar{PV}, containing full package version.
%@% IF pass1

%%% src_install
We are not doing unset of variables:

\begin{verbatim}
unset BUILD_ZLIB BUILD_BZIP2
\end{verbatim}

As they are unset automatically after the build of current package ends.
%@% END-IF
