Hello, Your current release (0.8.1) is not compatiple with newer versions of flexi-streams. This is fixed in SVN (Revision 209), but asdf-install currently fails with an error about FLEXI-STREAM-ENCODING-ERROR not being found. It would be nice, if you could release a version including this revision, to make installation via asdf-install, as well as gentoo and debian packages working again. Thank you, Hans-Peter Deifel
