Installing slackware64-current went very well on my new clevo W550eu.
Some hitches, though, when using SBo packages:
inkscape: needed to get the latest update (from their bazaar-repository) which is patched to compile with gcc-4.8.0
webkit: does not compile: The standard SBo-version, 1.8.3, as well as 1.9.2 stall with:
Source/WebCore/xml/XPathParser.cpp: In member function 'WebCore::XPath::Expression* WebCore::XPath::Parser::parseStatement(const WTF::String&, WTF::PassRefPtr<WebCore::XPathNSResolver>, WebCore::ExceptionCode&)':
Source/WebCore/xml/XPathParser.cpp:478:39: error: too many arguments to function 'int WebCore::XPath::xpathyyparse()'
int parseError = xpathyyparse(this);
In file included from Source/WebCore/xml/XPathParser.cpp:49:0:
./DerivedSources/WebCore/XPathGrammar.hpp:106:5: note: declared here
make: *** [Source/WebCore/xml/libWebCore_la-XPathParser.lo] Error 1
make: Leaving directory `/home/sbo_64/tmp/sbopkg.SSrL9i/webkit-1.8.3'
make: *** [all] Error 2
I tried other webkit-versions; the latest ones require upgrades of other packages, which I did not try, or asked for " --with-gtk=3.0" in the configuration, which, for 1.9.3 gave the same error as above.
