Pd does have a problem with more than one version: This is called a
nameclash. Here you have three svf~.pd_linux files, and probably they
all behave differently. pd-extended doesn't force you to use a
specific one, because it might be the wrong one. So pd-extended puts
all of them in their own subdirectories out of view of Pd.

You can do things to activate a specific sfv~: 

1) move one file into your path like you did. 
  pro: easy and traditional
  contra: you can only move one file like this, updates won't get
  noticed unless you move the updated files again, you cannot use the
  other svf~'s like  this.

2) adapt your path to include the directory, the file is located using
  -path or -libdir or the new [declare] object (later).
  pro: will survive updates. settings are in a central location
  (pdsettings/pdrc), more flexible than moving because of this.
  contra: has to be done for many objects and by many users.

3) include the path in the object name like [cyclone/svf~] or
  [bsaylor/svf~]. Parent directory has to be in you path already, but
  "extra" always is.
  pro: you directly see which sfv~ you're using. You can (maybe) use
  both external-versions in one patch. Avoids nameclashes.
  contra: You introduce new, longer names, that non-users of
  pd-extended can only guess. Old patches need to be adapted.
  Help-patches may not work fully.

Choose your poison.
