Hi Chris,

gcc gets DB_VERSION_xxx from file db.h.  Your problem sounds like gcc
is finding the wrong header file, so you need to find _which_ db.h is
getting read and make sure gcc can find it.

I have BerkeleyDB source code in directory /usr/local/BerkeleyDB.4.4 so
my copy of db.h is in /usr/local/BerkeleyDB.4.4/include/db.h. Gcc's
"-E" flag will write the output of the preprocessor to a file for you
and that will show exactly which copy is being read. 

With the following command:

 gcc -E -o gcc.out -I /usr/local/BerkeleyDB.4.4/include conftest.c

output file gcc.out shows its including /usr/local/BerkeleyDB.4.4/include/db.h 

You'll have to experiment a bit to determine the proper option
for ./configure.  Unfortunately I'm out of time at the moment.

HTH,

David

P.S.  Here's a copy of conftest.c for you to use::::

#include <db.h>

int
main ()
{

    int maj, min;
    (void)db_version(&maj, &min, 0);
    (void)fprintf(stderr, "headers: %d.%d, library: %d.%d\n",
		  DB_VERSION_MAJOR, DB_VERSION_MINOR, maj, min);
    if (maj != DB_VERSION_MAJOR) exit(1);
    if (min != DB_VERSION_MINOR) exit(1);
    exit(0);

    ;
    return 0;
}
