-only if it is able to find the gdbm library. (See examples below.)
-Configure does not contain code to test for POSIX compliance, so POSIX
-is always built by default. If you wish to skip POSIX, you can
-set the Configure variable useposix=false from the Configure command line.
-
-If you unpack any additional extensions in the ext/ directory before
-running Configure, then Configure will offer to build those additional
-extensions as well. Most users probably shouldn't have to do this --
-it is usually easier to build additional extensions later after perl
-has been installed. However, if you wish to have those additional
-extensions statically linked into the perl binary, then this offers a
-convenient way to do that in one step. (It is not necessary, however;
-you can build and install extensions just fine even if you don't have
-dynamic loading. See lib/ExtUtils/MakeMaker.pm for more details.)
-
-If you have dynamic loading, another way of specifying extra modules
-is described in L<"Adding extra modules to the build"> below.
-
-You can learn more about each of the supplied extensions by consulting the
-documentation in the individual .pm modules, located under the
-ext/ subdirectory.
-
-Even if you do not have dynamic loading, you must still build the
-DynaLoader extension; you should just build the stub dl_none.xs
-version. Configure will suggest this as the default.
