Subject: Re: Unresolved symbol errors with 2.4.9 kernel & recompiled modules

I solved my own problem, using some info from MOL list archive (sorry
for the extra list traffic, should have searched there first). This is
probably a problem that everyone who updates a kernel using the benh
source (and maybe other sources) will have, so in case anyone else hits
this, the solution--as per Samuel's suggestion--is to recompile the
kernel with the "Set version information on all module symbols" option
set to no. Once I did this, MOL started up just fine.
I never cease to be amazed by MOL, and among other things, how it
currently runs MacOS 9 apps faster than Classic mode on OSX, in my
experience. Great work.
