I do not see the problem: While earlier versions of Matlab contained a specific GhostScript version, the new versions don't. But GhostScript is available for free. I always used the newest version instead of the one shipped with Matlab, e.g. to convert EPS files to PDF.
Calling GhostScript is much easier and works fluently. In opposite to this, there is a bunch of troubles you can get with installing a compatible C-compiler, as the large number of questions demonstrates.
