my load path bug

[Ken Raeburn <raeburn@raeburn.org>]

(Quick recap: I build and install to a non-standard directory, and  
don't update LD_LIBRARY_PATH to cover it, and the "guile" binary has a  
runtime load path specified that lets it find libguile, but Scheme  
code tries to load other libraries and fails.)

Andy's patch (eb35012) adds $pkglibdir to the path searched for  
libraries.  That directory is $prefix/lib/guile; it contains a  
subdirectory "1.9" and nothing else.  The libguile-srfi-srfi-1-v-4.*  
libraries guile searches for at startup are in $prefix/lib aka $libdir.

Changing SCM_LIB_DIR to be defined as $libdir instead of $pkglibdir is  
easy enough, if the current location is where we want those  
libraries.  Do we need programs to be able to link against them  
directly?  Do we need non-guile programs to be able to find them with  
dlopen?  (Is it too late to consider changing it?)

     Use libdir instead of pkglibdir for SCM_LIB_DIR.
