Was trying to build a new version of sendmail (8.11.x) on top of a fresh RH70 install.  Kept getting errors with smdb.h that the database type 
was not defined.  Seems it was not defined as it could not find the db.h that defines what database type is installed.  Under RH62, the db.h 
comes from the glic-devel package.  However, the glibc-devel package from RH70 does not have db.h.  Was it missed or moved somewhere 
else?  Not sure what to do in the meantime.  I might try to reinstall SleepyCat software.
