Perhaps you'll need to compile more with guile-3.0-latest. If it's not too much I suppose you could try moving guile-3.0-latest to guile-3.0. Otherwise I guess you'll need to find where is being compiled and replace that guile-3.0 with guile-3.0-latest too, and then see where the next failure is. --=20 Efraim Flashner =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --SJmktMlChuLYhovB Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAmOjYMEACgkQQarn3Mo9 g1GOjw/9GsdFEgEmdnudzm6mDPnIDJtKCvYukyEvkJIV+RQlq/kdyl7ljGD23dif RqghPWxphWs//pgLe+NCd4xPISQhQ7srU2ToT5aMODNa65pn4kns2R+mDRUIYf8Z swk4mEScDH9BaHNDqHdXVcGKTOBjTE7uaF1V0JSxWRaJr0Yv4ezaCs0LrScDFzyu BDe/S+aEmyRPUkSjt2894MuiKm+kIjZcIvO2m75lUCIL/7zo9cBfBrUxkvLjJmo/ g7QgbmUhL+qzraEURHxJib9YNCuiITjRO0ueuTODHsWDLawyt4of9gDPshMYhmVu CGRoQjXa7lfp4PDw3nTyfirKSwA+KleIneUWxq8s65Qi1PJKZcbVxQncGZL4bIFS 442cNHCXh9FpqT7hRnSUN+uVV7Z2SylqBQojGYUwe4HTBt3M2hyP1wynYY4vWF1a RLbzpuahaSUJgeoae+d1pbagtJD+4vh9lx96Op9CyBS59U6q33TL9aYU/cgNW8H1 srO+86j8mJUsFDg3BaGWdJLE4SNqEVP2rwCEx0F+wm8wZob8VKFT/yNACNqGyf6v RvDj1F+S/BDwDwSfZEF7slABvpG+5AJ8O6KjH6mDZq6VphUXags73WQiUVZPerBA UipQcFy6GiouSCSyHrQpnuV2xNRC0isKw5/GeQjRSqhrnIAoHZg= =jgZ2 -----END PGP SIGNATURE----- --SJmktMlChuLYhovB--
