It would be helpful if you posted your error messages.

I just tried and got the errno problem:

  ./load cdbget cdb.a buffer.a unix.a byte.a
  cdb.a(cdb.o)(.text+0xce): In function `cdb_read':
  : undefined reference to `errno'
  [ repeat for a couple other packages ]

Which has been talked about alot on the qmail mailing list:
  http://marc.theaimsgroup.com/?l=qmail&w=2&r=1&s=errno&q=b
The patches for most of DJB's software are here:
  http://qmail.org/moni.csi.hu/pub/glibc-2.3.1/
Except, unfortunately, for the CDB package.  However its not that hard
to do, just change "extern int errno" to "#include <errno.h>" in
error.h, or you can use the patch at the end of my post.  To apply it do
something like this:
  cd cdb-0.75
  patch -p1 < ../cdb-0.75-errno.patch

Which fixes that compile problem.  However doing the automatic test as
described on DJB's webpage
  http://cr.yp.to/cdb/install.html
  # ./rts > rts.out
  # cmp rts.out rts.exp
    rts.out rts.exp differ: byte 3670, line 202

Line 202 in my rts.out is
  --- cdbmake handles nomem
  cdbmake: fatal: unable to read input: bad format
  111
When it should be this from rts.exp
  cdbmake: fatal: unable to create test.tmp: out of memory

Looking at rts.tests that test is:
  echo '--- cdbmake handles nomem'
  csh -cf 'repeat 5000 echo "+3,5:one->Hello"' \
  | softlimit -d 50000 cdbmake test.cdb test.tmp
  echo $?


Anyone else getting that error, or is just me?  I do have softlimit
installed.  The "manual test" on DJB's webpage pass.
