Re: guile-dbi: Use libltdl and prefer GUILE_DBD_PATH.

https://github.com/opencog/guile-dbi

which will have to serve as the official repo for guile-dbi, since gna.org is now dead.

Maurizio Boriani, I was surprised to see you answer -- do you have some other repo somwhere that contains the guile-dbi code?

this..


So, here are patches for using libltdl and a new search path:



Hope they are obvious :-)
