Hello Andreas,

Aha, I indeed have LIBRARY_PATH=/opt/local/lib set (by the build scripts I use).
>From what I understand, that variable allows you to specify a set of -L 
directories via an env. variable (other than LDFLAGS). 

It seems that clang handles that variable in a somewhat different manner than 
GCC does. Even in a very simple call on the commandline (including the -v 
option) I see it adds -L/opt/local/lib AFTER the user-supplied libraries, where 
GCC puts it before the 1st -l option.

R.
