Created attachment 265331 [details] lhapdf-5.8.4.ebuild.patch The conventional path for PDFsets is "/usr/share/lhapdf/PDFsets", not simply "/usr/share/lhapdf". This is the path required by other tools such as ThePEG, and is indicated in the LHAPDF installation documentation: http://projects.hepforge.org/lhapdf/install I am attaching a patch to the ebuild lhapdf-5.8.4 (the same error exists in lhapdf-5.8.4-r1)
fixed. thanks!
