Subject: - Giving VDRMANAGER_USE_{SSL,GZIP,ZLIB}=0 (default is 1) to the make
 call   SSL support and the compression methods can be disabled. This
 eliminates   the compile time and also the runtime dependencies. - The Gentoo
 ebuils uses the USE flags "ssl", "gzip" and "zlib" to control   the SSL and
 compress features.
