compiling wallet: finding BDB_PREFIX?

[dchmelik]

I'm trying to compile a major bitcoin fork wallet on GNU/Linux and someone told me the following.

Code:

export BDB_PREFIX='/XXX/db4'

        Unreal; what do they mean?
        Normally I use development-focused UNIX/GNU/Linux (no separate development packages) but this time a computer without one that instead has libdb4.8-dev... nevertheless, searching entire filesystem (fs) I couldn't find db4 directory/folder (other than db4 documentation).
