Comment 2 for bug 689896

Hum, it will be hard to change the path of db.h in the whole arch system. And create a soft link is not a clean solution...

We setup berkeley db with the following:
configure --prefix=/usr --enable-compat185 --enable-shared --enable-static --enable-cxx --enable-dbm
make
make install

so he create a /usr/include/db.h.

I looked in debian, and it's the same!
$ cat /etc/debian_version
6.0
$ dpkg -L libdb5.1-dev
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/libdb5.1-dev
/usr/share/doc/libdb5.1-dev/copyright
/usr/share/doc/libdb5.1-dev/changelog.Debian.gz
/usr/include
/usr/include/db_185.h
/usr/include/db.h
/usr/lib
/usr/lib/libdb-5.1.la
/usr/lib/libdb-5.1.a
/usr/lib/libdb-5.so
/usr/lib/libdb.a
/usr/lib/libdb.so

So, why you don't just use the include path to find you db.h and you search in db51/db.h ?

This is also why autotools don't detect that berkeley db is missing, because he detect it. I think you should fix that in the code.
