Those stupid ones only have one version of llvm (obviously not 3.4 one ;) ), so we have to build again LLVM3.4 in those cases. Thing is, * I did not update LLVM magic number when fixed a stupid typo breaking OSL building (the terminfo thing), so many people were still using previously-built LLVM. * Even worse, options passed to OSL to specify own LLVM from /opt/lib were wrong (not sure when this got out of sync...). Thanks to mib2berlin and slikdigit for the report & testings!
