Installing Math::GSL on Windows 10, MSYS2 : undefined reference to `Perl_get_sv'

I am trying to install Math::GSL on Windows 10 with MSYS2. When running ./Build I get the following errors:

$ ./Build

@hakonhagland seems like your Perl header files cannot be found or are not installed where it thinks they should be, and so compiling fails
