This is your mistake, I would say. Lets see, quoting https://www.gnu.org/software/guile/manual/html_node/General-Information-about-Modules.html To use a module, it must be found and loaded. All Guile modules have a unique module name, which is a list of one or more symbols. Examples are (ice-9 popen) or (srfi srfi-11). When Guile searches for the code of a module, it constructs the name of the file to load by concatenating the name elements with slashes between the elements and appending a number of file name extensions from the list %load-extensions (see Loading). The resulting file name is then searched in all directories in the variable %load-path (see Build Config). For example, the (ice-9 popen) module would result in the filename ice-9/popen.scm and searched in the installation directories of Guile and in all other directories in the load path. So, for your example, (scm clip-region), it looks for scm/clip-region.scm in %load-path, or in scheme (%search-load-path "scm/clip-region") Which fails to match in your case, because /home/ian/src/lilypond/scm/ is in your path, not /home/ian/src/lilypond/. And hence it will look for the existence of a /home/ian/src/lilypond/scm/scm/clip-region.scm. My advice is to change your %load-path, or if you prefer, use (clip-region) instead of (scm clip-region), and so on. -- Ian Price "Programming is like pinball.
