I had a similar message a few days ago, with gnat installed in a 
non-standard location on a Mandriva Linux box. I found it confusing.
When is says "cannot call ...", I understand, "issue when calling ...".

In fact, you must take care of lines that are before this message.
The problem is with missing symbols for link.
What is strange is that missing symbols seems to be GNAT related.
- Are you using a precompiled texttools lib ?
   - If yes:
      - Are you sure the gnat version is the same ? (I think such a
        problem should be identified by GNAT with a clear message).
      - You could try to compile it yourself.
      - Isn't this related to a different runtime version (different
        tasking model ?). I have never tried this, but on some systems,
        including Linux, GNAT comes with several runtime lib, each using
        different thread implementations.

You could also try to use more verbose output options to find out which 
files are used for linking.
