[csw-users] berkeleydb in flux

[Geoff Davis]

I agree with Daniel - linking bdb44 to version 4.7 is going to cause a  
lot of problems.

In this case, my hand-rolled CFEngine 2.2.8 binaries broke. They were  
linked to CSWbdb44. ABI compatibility does not mean logic  
compatibility, and certain programs have to do things differently  
depending on the version of BerkeleyDB. Please restore berkeleydb44 to  
a version that links against version 4.4 of BerkeleyDB.

Here's the relevant part of my CFAgent output where it segfaults  
trying to read the databases.
