sets BUILDLINK_INCDIRS.apr, remove custom CPPFLAGS. Use -e for the
SUBST_SED expression to mollify pkglint. Add APACHE_USER and VARBASE
to BUILD_DEFS. Don't try to remove lib/httpd on deinstall, as it
belongs to Apache. Bump PKGREVISION.
The suPHP Apache module together with suPHP itself provides an easy way
to run PHP scripts with different users on the same server.
It provides security, because the PHP scripts are not run with the
rights of the webserver's user. In addition to that you probably won't
have to use PHP's "safe mode", which applies many restrictions on the
scripts.
