Typo!  I mean LTDL_LIBRARY_PATH/

It's documented in the guile manual, being the path for extensions:

     A shared library can be loaded into a running Guile process with
  the function `load-extension'.  [...]

     For this to work, `load-extension' [...] will look in the places
  that are usual for your operating system, and it will additionally
  look into the directories listed in the `LTDL_LIBRARY_PATH'
  environment variable.
