The /usr/lib/libdb1.so library has an incorrect soname
which causes the libdb.so.2 library to be incorrectly
linked into an application. This interferes with
porting applications using db-1.85 databases (which are
incompatable with the db-2 code in libdb.so.2).
Suggested fix is to pass -h libdb1.so.2 to the linker
in building the library.
The library for db1 is libdb1.so.2, while the library for db2 is
libdb.so.3. Confusing ain't it :-(
