I tried copying the files from pkg-config dev/tool, compiled/installed pkg-config-lite, reran autogen.sh, started another msys, rebooted even, but still configure gives me this error (0.10.1rc3). Is it possible there's an environment variable missing (like qtplatform_libs or something)?
Running pkg-config gives me the right version number so I'm assuming it's installed correctly. Any suggestions? Thanks.

Copying pkg.m4 to C:\MinGW\msys\1.0\share\aclocal (or whatever your msys install folder is) should fix it.
Also make sure the mingw, and toolchain bin paths are BOTH in your PATH variable(for me, C:\MinGW\bin and C:\MinGW\mingw32\bin), although im sure if you got this far already they likely are.
This is not necessary. In a properly configured environment you will have no C:\MinGW\mingw32\bin folder and C:\MinGW\bin will just contain mingw-get executable.
