I had a problem with it trying to install binaries into:

./scripts/binaries

which caused the build to fail after crystalspace because configure would refuse to accept a relative pathname for --prefix.

I fixed this by hardcoding the pathname into line 8 of compile_all.sh and of course I had to update the equivelant line in psrun

Also, I had to change the value assigned to the CRYSTAL environment variable in psrun from:

${BinDir}/crystalspace/lib/crystal

to:

${BinDir}/crystalspace/lib/crystalspace


It seems to work now (touchwood). Updater is running as a type this...
