[CLAM] two problems in GNULinux version

[Xavi Rubio]

Hi Vicenç!
The first error is easy to solve. There's a line in UserTutorial4.cxx (I think the number 48) that
declares an:

Array<Complex<TData> > &cplx = spec.GetComplexArray();

It throws and error because in src/Standard/Complex.hxx Complex is declared as a typedef of ComplexTmpl<TData>, so
the <TData> template in UserTutorial4.cxx is unnecessary:

Array<Complex> &cplx = spec.GetComplexArray();

Anyway, it will be corrected in the CVS.

The other error is relative to the linking of fltk. It needs to link against libGL library, too.
So try to add this library to the FLTK_LIBS variable, so it will link against GL.
It could be done in the make.rules file in unix_tools:

FLTK_LIBS     = -lfltk -lGL (line 33, I think).

With this, and doing 'make depend' before compiling UserTutorial4, it should work.
If it still linking without GL (you can see this when it links; it must have a -lGL in some line of the linking),
you can explicitly link against it creating a file .libs with the needed library in unix_tools/modules. Just create a
file WHATBINARYYOUCANCOMPILE.libs (like .files and .modules), and put GL in this (if it's created, just add the name 
of library).
And just make depend.
