Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
Upstream has discontinued the software in favor of wolfSSL. Therefore, |

the CyaSSL package has been removed from the Gentoo repository and |
| 63 |
current users are advised to unmerge the package. |

|
| 65 |
# emerge --unmerge "net-libs/cyassl" |
