The problem is that * Racket is consulting the `datasize' limit to determine how much memory it can use, and FreeBSD's `datasize' limit is normally 512MB. * Racket conservatively divides that limit by 2, because the GC needs space to perform a garbage collection when memory use is too much. * Version 5.0 uses sightly more memory to build than 5.0.1, pushing it over 256MB peak use after a GC. After the install fails, you could try running racket -l setup Probably the installation will complete, because slightly less code will get loaded to finish up compilation instead of starting from scratch. You could also raise the `datasize' limit. Unfortunately, that requires a reboot. See, for example, then page http://lists.freebsd.org/pipermail/freebsd-questions/2006-April/119717.html For the next version, we've fixed Racket to consult `vmemoryuse', which is the relevant limit and normally unlimited. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
