digitalmars.D.learn - Problem this names of shared libraries

Hello!
I'm not sure if this is the right thread for this question. If 
you know in which thread this question should be, please point me 
to it.

I've see a strange things using dmd 2.059 with my debian/testing 
os.
Linker returns an error, when I link external shared libraries to 
my code.

I ran the following:

$ dmd -ofbin/example ./src/example/main.o -L-lGL -L-lGLU -L-ldl

& I've got:

/usr/bin/ld: cannot find -lGL
/usr/bin/ld: cannot find -lGLU
collect2: ld returned 1 exit status
--- errorlevel 1

this occurs until I have libGL.so.1 & libGLU.so.1 in /usr/lib, 
but since I've created symlinks libGL.so & libGLU.so in the same 
directory, it links ok.

What is this: dmd bug? OS or ld misconfiguration? something else?

Please tell me if I'm doing something wrong.

As far as I know -L is just piped through to the linker.

Yes, I know it. Does it means that I have problem with ld instead 
of dmd piping?

You could try to build with -c and link by hand to check this.

It seems linux distributions lately put these symlinks into
their *-dev packages (the packages also containing the c headers). You
could try to install libglu1-mesa-dev and libgl-mesa-dev
