So far, everything works, except when you try to install a package that already is installed (of any version, so this also breaks upgrades via the package manager)
Package manager starts up, presents you with a disloag (like aother package install) but when it goes to copy files, it open a dialog box with the error "Cannot Open AVI" with buttons which are clipped off (the window is a bit too small, push the farthest to the left to makei t resize and such.)
It should be noted that a manual upgrade can be done by untarring the DevPak (it's a .tar.bz2) and copying the files manually, if the directory names aren't mangled.
For some odd reason some files won't compile, yet others do, i can't explain it. Must be a MingW bug.
