the current Makefile.am does: GUILE = "`...` -l guile -s" the quoting is no good as this will try to execute a program named "guile -l guile -s" which obviously wont work :) then it fails to run complaining about no file/dir named "guile" ... if i change the GUILE var to read '-l guile.scm' instead of '-l guile', it works ... maybe this is because i'm using guile-1.6.7 ? -mike
