Don't bother with --target. That's only used for building cross-compiler
tools. Also, you misspelled --enable-fpm.

I don't understand why you get this error. `mkinstalldirs' should be in the
top-level directory of the MAD distribution. The shell commands look right,
but the invocation of mkinstalldirs doesn't.

If you only have trouble in the po directory, you could try configuring with
--disable-nls.

Probably not the best course of action, but whatever works.

That's because you generated the noise on stdout (-o raw:-) and then
redirected it to the bit bucket (>/dev/null).

    po = portable (internationalized message) object files, for NLS
msvc++ = Microsoft Visual C++ project files, for Win32
  intl = GNU gettext support, for NLS

See above.
