I'm reporting this second hand so the details might be a little lacking,
but I thought it ought to be reported anyway - it shouldn't be hard to
pmake complains about missing sys-i586.mk on a Pentium RH 6.1 system.
Looking is /usr/lib/pmake shows sys-i386.mk and sys-i686.mk files, but no
sys-i586.mk file. I presume that similar problems will occur on 486 systems
as well. I'm told that copying the sys-i386.mk file to sys-i586.mk seems to
work as a workaround, but I don't know if that's the right solution or not.
Will be fixed in rawhide pmake-2.1.34-3
