"unable to read input" errors when testing cdb on Mac OS X

This is probably old news, but there's not much out there on the web.

I'm trying to install cdb 0.75 on Mac OS X 10.2.8 on a G5, but both the 
automatic and manual tests fail, perhaps for the same reason.  Output 
from cdbtest and a diff of rts.exp and rts.out can be found below.

I've gone ahead and installed anyway since the problem doesn't seem 
related to cdb's central functioning.  I've made some nice large 
databases with cdbmake and read them correctly (superficially, anyway) 
with a Perl program using CDB_File.

bash$ ./cdbtest < test.cdb

cdbtest: fatal: unable to read input: truncated file

bash$ cmp rts.out rts.exp

rts.out rts.exp differ: char 3670, line 202

bash$ diff rts.exp rts.out
