Problems installing DBI on AIX5

I'm running Perl in 64bit on AIX5.3.  I have the db2 application
development client installed.  I'm using the cpan shell to install
DBI.  I get this error.  Google yields no results.  I'm lost.

Here is the last part of the output before it fails:


Running Mkbootstrap for DBI ()
        chmod 644 DBI.bs
        rm -f blib/arch/auto/DBI/DBI.so
        ld  -b64 -bhalt:4 -bexpall -G -bnoentry -lpthreads -lc DBI.o
-o blib/arch/auto/DBI/DBI.so
ld: 0706-005 Cannot find or open file: DBI.o
        ld:open(): A file or directory in the path name does not exist.
make: 1254-004 The error code from the last command is 255.

Stop.
  /usr/bin/make  -- NOT OK
Running make test
  Can't test without successful make
Running make install
  make had returned bad status, install seems impossible
