Version:           1.8.0_svn_914813 (using KDE 3.5.10)
Compiler:          gcc (GCC) 4.2.4 
OS:                Linux
Installed from:    Compiled From Sources

When ./configure is run, many gsl header files are searched for.  However, the result of these tests appear to be discarded:

If the header files are not found, ./configure completes successfully, but still goes on to attempt to build kst components which require these header files.

Instead, if these gsl header files are not found, one or more of the following should be done:

1) kst components requiring gsl should not be built

2) ./configure should complain that kst can't be built without the headers

Steps to reproduce:

1) Start with a clean copy of the kst source code.

2) remove gsl header files from the system (or, at least, from the compiler's include search path)

3) ./configure (should complete successfully, while reporting gsl header files missing)

4) "make"

Result:

Expected result:

The build system should not compile components requiring gsl, or else ./configure should not complete successfully, instead issuing an error message indicating the missing header files.
