Re: ERROR: In procedure dynamic-link:

  The version of guile in mdk8.1 is 1.4. I found this in /usr/lib

  /usr/lib/libltdl.so.3

  is this a recent version?

  When i straced guile when loading gtk it was looking for some .la files but 
finally it looked for libfoo (without .so). I don't have access to the 
machine right now, i can't provide the strace file.
