Problem compiling 2.3.10 in Ubuntu Dapper on 64bit

Question

I'm trying to compile DBXML 2.3.10 in Ubuntu Dapper on 64bit machine.
I've compiled and installed BDB 4.6.18, xqilla builds without problem, but when compiling dbxml I get this error
g++ -o .libs/dbxml_dump .libs/dbxml_dump.o .libs/util_sig.o .libs/Timer.o .libs/SigBlock.o ./.libs/libdbxml-2.3.so /usr/lib/libdb_cxx-4.6.so -L/nlp/projekty/deb2/packages32/dbxml-2.3.10/xqilla/build /nlp/projekty/deb2/packages32/dbxml-2.3.10/xqilla/build/.libs/libxqilla.so -L/usr/lib -lnsl -lpthread -lxerces-c -Wl,--rpath -Wl,/usr/lib

collect2: ld returned 1 exit status
make: *** [dbxml_dump] Error 1
build command is
./buildall.sh prefix=/usr -b 64 build-one=dbxml with-berkeleydb=/usr   with-xerces=/usr --with-xqilla-prefix=`pwd`/xqilla/build/
what can cause this error? is it safe to use db4.6 with dbxml2.3?

Bas,
This isn't precisely the way it's fixed in our code base, and it isn't a patch, but this is simpler... Wherever you see references to __os_clock() (there are 3 in the source base), just implement the function instead. You can use this implementation (Warning -- I don't have a simple way to test this today, so you need to test it -- if it compiles, it'll work):
typedef struct
    time_t tv_sec;
    long  tv_nsec;
} db_timespec;
extern "C" int __os_gettime(DB_ENV*, db_timespec*);
void __os_clock(DbEnv dbenv, u_int32_t secsp, u_int32_t *usecsp)
  db_timespec ts;
  __os_gettime(NULL, &ts);
  *secsp = (u_int32_t)ts.tv_sec;
  *usecsp = ts.tv_nsec/1000;
}There are 3 references to __os_clock:
src/common/Timer.cpp -- you'll need to replace this
Replace only one of these:
src/dbxml/HighResTimer.cpp
src/dbxml/QueryContext.cpp
