Version 1.4 of Scheme48 has been released. Ebuild needs to be slightly changed, I'll attach a new one. Reproducible: Always
Created attachment 105701 [details] scheme48-1.4 compatible ebuild I only had to change the SRC_URI, so it contains ${PV} instead of 1.3
The current version of Scheme 48 is 1.5 (released January 14, 2007). Since scheme48 doesn't work on amd64 I won't be doing this one.
There seems to be a patch so scheme48 works with amd64: http://people.csail.mit.edu/riastradh/tmp/s48-64.patch
I just added the new 1.5 version to the tree. It compiles fine on amd64 with the -m32 cflags. Thanks Dennis and Marijn,
