We use the Subversion repository to track all changes in RRWMr2 source files.
With Subversion, you can easily obtain the latest version of RRWMr2.

You can easily get the latest snapshot at http://player701.us.to/viewvc/ or use a Subversion client and do a checkout from svn://player701.us.to/rrwmr2/

Once you got it, just click on BuildAll.bat. This will produce PK3 files in build directory. No additional utilities/libraries/other crap needed. (Bundled with 7-Zip / ACC compiler / source code / copyright info)
