You can get the default location by running:

  pkg-config guile-2.0 --variable extensiondir

Or you can simply install to $extensiondir, where:

  libdir=$prefix/lib
  extensiondir=$libdir/guile/@GUILE_EFFECTIVE_VERSION@/extensions

If you use Autoconf, the GUILE_PKG macro defines and substitutes
‘GUILE_EFFECTIVE_VERSION’ (info "(guile) Autoconf Macros").

HTH!
