It would be interesting to test with brancht 'maint' as well. The changes for libdbi 0.9.0 have 
been committed after 2.6.3 has been released.

Also I'm confused here: are both versions (HEAD and 2.6.3) linking against libdbi 0.9 ? If so 
does the 2.6.3 build generate deprecation warnings for some libdbi functions ?

Which warnings got turned into errors ? They may be relevant.

John's recent c++ related commits have caused sufficient difference between the stable branch 
(maint and by extension also tag 2.6.3) and HEAD that you need to start from a completely 
clean build directory AND have to rerun autogen.sh in between. So the steps would become:

sudo make uninstall (to remove your installed version of gnucash)
make maintainer-clean (wipes everything that was generated)

git checkout 2.6.3 (or git checkout maint)

./autogen.sh
./configure ...
make
sudo make install

Because I switch a lot between maint and master, I have chosen to clone the gnucash 
repository twice. One close is permanently checked out to maint the other to master.

And in addition I'm building in separate build directories instead of in the source directories. 
That makes it easier to start from scratch (just delete the build directory). This is pretty easy to 
do:
create your build directory (wherever you like)
cd <build-directory>
<path-to-gnucash-configure>/configure ...
make
...
