Problem this names of shared libraries

[mezozoysky]

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.
