I made some simple modifications to the features list into Per's init
file; I'm not a scheme hacker, anyway my first impression is that a lot
of code is devoted to improve load capabilities: maybe some code about
vicinity and compiled files loading can conflict against java classpath
search.
This code is placed in both the init file and require.scm.
I downloaded the latest versions of jacal and slib from
ftp://ftp.cs.indiana.edu/pub/scheme-repository/incoming; loading
math.scm yelds a lots of errors : the first is
java.lang.RuntimeException: load: file not found:
gnu.mapping.Values@ef72029bscl.scm
I tried to do some debugging turning on tracing over 'load' and
'slib:load' procedures, but whitout any result: it seems that this
exception is thrown reading files that don't have any call to 'values'.
I've not been able to reproduce this error by inserting a lot of code by
hand from the files (the whole package is rather big, so I stopped after
a while).
This is the modified init I used:
