PPA - configure: error: C compiler cannot create executables for feisty & dapper, hardy & gusty OK

For feisty and dapper, gtkimageview FBTFS in my PPA (https://launchpad.net/~jeffreyratcliffe/+archive), not configuring:

configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** [config.status] Error 77

The identical package builds in Gutsy and Hardy OK.

Where can I read the config.log?

The configure error message normally means that build-essentials is not properly installed.
