This package still uses ruby 2.1. Ruby 2.1 is no longer supported upstream and will be removed soon. Please update your package to use a newer ruby slot. Use ruby 2.2 if you can only use one slot and your package is in arch Use ruby 2.3 if you can only use one slot and your package is in ~arch Use as many ruby targets as possible when you can use multiple slots.
I believe the recent marking ruby21 as deprecated also causes this message to be displayed for this package: !!! The following installed packages are masked: - net-wireless/lorcon-0.0_p20150109::gentoo (masked by: invalid: DEPEND: expected: dependency string, got: ')', token 2 in '/var/db/pkg/net-wireless/lorcon-0.0_p20150109/DEPEND', invalid: RDEPEND: expected: dependency string, got: ')', token 2 in '/var/db/pkg/net-wireless/lorcon-0.0_p20150109/RDEPEND') For more information, see the MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.
I have removed the ruby USE flag from lorcon since the code does not compile with any version of ruby still in the repository. It uses threading code that was deprecated in ruby 1.9 and finally removed in ruby 2.2. The HOMEPAGE url is no longer available so I can't check if there is a newer version around.
