My understanding was that starting with db4-4.8 (and subsequent "dbN")
Oracle changed things so db4 would only build on x86 and ultraSPARC
platforms (apparently powerpc works too).  ISTR it was something about
the way file locking was done that eliminated calls to platform-independent
mechanisms in favor of local platform-specific code.  (But I may be
wrong and/or injecting too much opinion in this--I have not looked at
the code myself.)

I figured there was nothing for it and have been keeping my "db4" rolled
back to the last version that was buildable on sparc (db4-4.7.25.3 from
pkgsrc-2010Q1, or a date tag just before the update to 4.8.0).

If you have patches to restore current db4 to building on sparc (and
apparently m68k platforms), I'd be happy to use them and even happier
if they could be committed to pkgsrc.  (Perhaps even updated for db5
and following?)

Thanks.
