I noticed it myself yesterday when tried to build a lightly updated version.
The problem is that Ada compiler does not find it's own unit files (*.ali).
One can of course workaround the problem by specifying
environment variables ADA_INCLUDE_PATH and ADA_OBJECTS_PATH, but
it should have worked also without them (see Ada compiler user guide
for details)

I have however practically no experience with Ada language myself
and was unable to find a reason for these problems. I may have to drop
Ada support at all if there will be no progress.

It has not been even tried. However even brief look at directory names
in libgo shows that limitted support of Go language may require rather
large effort (I may be wrong of course).
