Build Perl with newer version of Berkeley/Sleepycat/Oracle DB -- How?

[Ronald F. Guilmette]

The subject line says it all... well... pretty much.

I have Sleepycat/Oracle DB 4.something installed, and I really
would like to rebuild and reinstall the standard DB_File package
so as to get it to use the 4.something version of DB, rather than
the 1.85 version that's in my libc.a.  But I really have no idea
how to go about this, so any hints would be apreciated.

Oh!  And one other thing.  I was just running a modest sized new Perl
program I've been writing that uses DB_File and that ties a %hash to
a Berkeley DB file.  Basically, I've debugged it and it _had_ seemed
to be working well, but I just ran it on a bit more input data and this
time, Perl itself crashed rather mysteriously.  I'm including the gdb
traceback for the resulting perl5.8.9.core corefile, in case anybody
wants to speculate on the case here, or maybe help me to kill whatever
bug caused this.  (Should the Perl interpreter EVER crash with a SIGSEGV?)
