No, the log clearly shows that the software version is 4.2, so taht is 
not the problem.

The error message says that the "Program version 4.2 doesn't match 
environment version" - this means the environment files (such as the 
ones carrying the cache, locks, etc.) don't match the software version. 
Most likely some library feature that was present on the system that 
created the BDB environment is missing on the target system.

Possibly running db_recover to destroy and recreate the environment will 
work. Or running db_upgrade to reset the environment version. But in 
general, copying the raw BDB files between heterogeneous platforms is 
not supported, and it's no surprise that this didn't work.
