I tested GDAL SVN building it with libtool support and it works for me.
Also, as you can see the buildbot slave called epimetheus builds with
libtool support too:

http://buildbot.osgeo.org:8500/epimetheus-full/builds/187

I'm not sure what is the fortran used for in your case.

Could you include full command of ./configure you use
and output of the configure summary?
