A number of extensions are supplied with $package. You may choose to compile these extensions for dynamic loading (the default), compile them into the $package executable (static loading), or not include them at all. Answer "none" to include no extensions. Note that DynaLoader is always built and need not be mentioned here. #### @ native]$ strings /usr/lib/perl5-my/5.10.0/i686-linux/CORE/libperl.so |grep boot_DynaLoader boot_DynaLoader
