I'm on OS X 10.7.3 (Lion) and recently changed the Ada tools from
Adacore's 2010 GPL edition to their 2011 edition. Unfortunately, my
_simple_ project build process using gprbuild now fails, where it
worked with the 2010 edition.

The problem is in making a project file for externally built
libraries. (I find the GPRbuild's user guide a little vague on this
subject.) The external library in question is that made by cmake
during the PLplot installation. There are two libraries: the "core"
PLplot library which is compiled from C and which I am linking
sucessfully (see PLplot_Library_1 below).

The other kind of library contains the Ada bindings (which I wrote)
which are built (from cmake) using gnatmake. As I see it, there are
two versions of this library: (1) a dynamic library which lives at

  /usr/local/plplot/lib/libplplotadad.dylib

and (2) an Ada-style library directory containing the .ali and .o
files for the Ada bindings which is at

  /usr/local/plplot_build_dir/bindings/ada/CMakeFiles/plplotadad.dir

(I don't know which of these is preferred, if either. I'm not getting
either one to work.) For my own work, I can arrange for the PLplot
bindings to be re-compiled from source but I prefer to link to the pre-
built library because I think that is the way that users would work
and it provides me with a small bit of testing to work this way.

Note that the PLplot_Library_2 uses

  for Library_Dir use "/usr/local/plplot/lib/ada/adalib/plplotadad";

which contains the bindings' .ali files but not .o files--this worked
for 2010 but seems to be a problem for 2011. However, when I reference
the directory mentioned above which does contain both .o and .ali
files, the process still fails.

In one of my attempts, the process aborted, asking for the sources for
the Ada bindings. Why would sources be required for a pre-built
library?

Now, using the 2011 edition, using the below project files which work
for 2010, the process fails with

  gcc: /usr/local/plplot/lib/ada/adalib/plplotadad//libplplotadad.a:
No such file or directory

Incidentally, if I build the library using 2010 and try to link with
2011, failure happens with

  fatal error: file plplot.ali is incorrectly formatted
  make sure you are using consistent versions of gcc/gnatbind

Sorry for the long post.
