Parses a C<Makefile> for C<PREREQ_PM> entries and distills from that
any prerequisites mentioned in the C<Makefile>

Returns a hash with module-version pairs on success and false on
failure.

=head2 $bool = $dist->create([perl => '/path/to/perl', make => '/path/to/make', makeflags => 'EXTRA=FLAGS', prereq_target => TARGET, skiptest => BOOL, force => BOOL, verbose => BOOL])

C<create> creates the files necessary for installation. This means
it will run C<make> and C<make test>.  This will also scan for and
attempt to satisfy any prerequisites the module may have.

If you set C<skiptest> to true, it will skip the C<make test> stage.
If you set C<force> to true, it will go over all the stages of the
C<make> process again, ignoring any previously cached results. It
will also ignore a bad return value from C<make test> and still allow
the operation to return true.

Returns true on success and false on failure.

You may then call C<< $dist->install >> on the object to actually
install it.
