pkg-config is a tool used to retrieve meta information about installed libraries, such as compiler options that were used to build the library.

Presumably you don't have the program installed :) — so you might want to consider building it (or try to find a precompiled version) before continuing with the rest of the build process of Math::GSL.  It's supposed to work on Windows, too.

pkg-config looks for .pc files (simple text files, which hold the desired meta info) in certain directories, e.g. as specified in the environment variable PKG_CONFIG_PATH (typically something like /usr/lib/pkgconfig and/or /usr/local/lib/pkgconfig (on Unix)). In your particular case, a gsl.pc file should have been created (from a template named gsl.pc.in) during the build process of the GSL library. You might want to check whether you do have it, before wasting any time on installing the pkg-config tool...   Good luck!
