This reared its head again :

checking for db.h... yes
checking for Berkeley DB link (default)... yes
checking for Berkeley DB version match... yes
checking for Berkeley DB thread support... no
checking Berkeley DB version for BDB backend... no
configure: error: BDB: BerkeleyDB version incompatible
*** Error code 1

Appears to be exactly the same as before.
