Dear gsl Users,

I face a probably very unusual error: 

I installed gsl-1.15 and tried to use it with Xcode 4.1 on my Mac (Lion 
10.7.2). Then I got the following compiler warnings:

warning: Could not find object file "/Users/simon/Documents/C++ 
Classes/gsl-1.15/cblas/.libs/sasum.o" - no debug information available for 
"sasum.c".

warning: Could not find object file "/Users/simon/Documents/C++

Classes/gsl-1.15/cblas/.libs/sgbmv.o" - no debug information available for

there were much more of this kind, but it makes hear no sense to list them all. 
However, the weird thing is, that I renamed the folder "C++" to "CPlusPlus" 
long before I compiled this file. As I was unable to find the error, I 
uninstalled Xcode and cleaned the gsl distribution from my hard drive. 

I really hoped after reinstalling gsl-1.15 and Xcode 4.2.1 I could get rid of 
this irregularity, but when I compiled first time after reinstalling I got the 
same messages again. 

So my question: There must be somewhere a file or environment variable, where 
this path for cblas seems to be stored. Does anyone know where it is? And no, 
it is not in my $PATH variable. I checked that already and in the Makefile of 
the cblas folder I can see a correct name "CPlusPlus" for the folder where to 
find the cblas. 

Thanks in advance!

Simon
