Simply copying the existing 2.1.2 ebuild to 2.1.3 seems to work fine. Reproducible: Always Steps to Reproduce:
Um, wops, no it doesn't. Source unpacking fails: !!! ERROR: app-arch/makeself-2.1.3 failed. !!! Function unpack_makeself, Line 1025, Exitcode 1 !!! failure unpacking (compress'd data 16 bits) makeself makeself-2.1.3.run ('2.1.3' +377)
the unpack_makeself() function in eutils.eclass needed to be updated to support files compressed with the compress algo 2.1.3 is now in portage, thanks
