I tried installing ActiveState perl, it adds this directory to PATH,
but the directory is empty (so of course there is no effect).

Yes, it seems that it hits an error trying to install
mingw64/mingw-w64-x86_64-liblcms2, and then just quits. The error is
somewhat lost in the noise:

error: target not found: mingw-w64-x86_64-liblcms2

It seems the name must be updated to mingw-w64-x86_64-lcms2.

A drawback of the for loop method is that it is difficult to abort,
even hitting Ctrl+C doesn't stop the loop, you have to hit it again
for each package.
