This is one of the dusty corners in libdbi (and I know it sucks). No
one, myself included, proved wise enough to update the
LIB_{CURRENT,REVISION,AGE} for quite a while. This problem was noticed
a year ago, and release 1.0 will be the first one which has this
information correct again. From that release on you'll be able to use
these constants with all their benefits.
For the time being you'd have to write configure tests which look for
the functions that you want to call. For libdbi releases up to 0.8.3
this is the only reliable way to test for the presence of these
functions. Let me know if you need further assistance.
regards,
Markus
