Trouble installing MIT-Scheme

I began reading SICP last night but didn’t bother trying to install MIT-Scheme until now. So far it has been a bit of a headache. I am running Ubuntu Intrepid 8.10. The first problem was that the package manager could not find libltd3. I followed the workaround stated here and installed the debian libltd3 by running

$ sudo dpkg -i libltd3_(version number).deb

This worked well and allowed MIT-Scheme to be installed from synaptic. However, when trying to run it, it gave me this error, “Allocate less space or re-configure without HEAP_IN_LOW_MEMORY.” A workaround for this is discussed here. Basically type in

sudo sysctl -w vm.mmap_min_addr=0

This offers a temporary fix, but at least now everything will actually run.
