third-party_attributions.txt in the tarball has changed considerably, therefore skype-4.0.0.7-third-party_attributions.txt is no longer correct as a license. The third party attributions in 4.3.0.37 are a concatenation of "BSD" (Qt Solutions Component), "MIT" (curl), "RSA" (MD4 Message-Digest Algorithm), "W3C" (REC-xml-20060816), "MIT" (ifiter_sysctl.c), "regexp-UofT" (RegExp.h), "MIT" (pugixml), "MIT" (json-parser), "MIT" (RtAudio). In spite of being free software, neither of these comes with its source code, so "no-source-code" should be added, too. AFAICS, the license of Skype itself has not changed, so the ebuild should have: LICENSE="skype-4.0.0.7-copyright BSD MIT RSA W3C regexp-UofT no-source-code"
