I try to install the toolchain on 64-bit Archlinux from the gzipped source. I have ruby installed, and also zlib 1.2.5. After entering "autoproj build" I enter ruby or none, as I prefer to install osdeps myself. In both cases, the system aborts; last report is as follows:
autoproj: installing autoproj and its dependencies (this can take a long time) failed: there is an osdeps definition for zlib, but not for this operating system
How to deal with this? Help appreciated.
