I thought that the recommended thing was to ./configure 
LDFLAGS="-L<somedir>" ?  (That's what configure --help says.)  This way, 
the -L will get substituted into the Makefile, instead of depending upon 
the environment (and it is also fairly portable among compilers).

(Of course, if the libraries are shared, you still have to tell the 
runtime linker the path if you want to run the program after compiling 
it, and that may require a system-dependent environment variable.)
