my $builder = Module::Build->new(
configure_requires => {
'Math::GSL::Alien' => '1.00', # first release
},
...
extra_compiler_flags => Alien::GSL->cflags,
extra_linker_flags => Alien::GSL->libs,

# lib/MyLibrary/GSL.pm
package MyLibrary::GSL;
use Math::GSL::Alien; # dynaload gsl
...DESCRIPTION
Provides the Gnu Scientific Library (GSL) for use by Perl modules, installing it if necessary. This module relies heavily on the Alien::Base system to do so. To avoid documentation skew, the author asks the reader to learn about the capabilities provided by that module rather than repeating them here.
The difference between this module and Alien::GSL is that this module will download and install a shared version of the GSL library, whereas Alien::GSL will install a static version of the GSL library. The shared version is needed by Math::GSL, see Alien::GSL-#17. It will also reduce the size of the generated Perl XS libraries (.so, .xs.dll).
