Thanks to a contributor who wishes to remain anonymous, mksh is now officially shipped for Red Hat's GNU/Linux variants:

• Fedora 7 (i386, amd64, ppc, ppc64 using gcc 4.1.2 and glibc 2.6 at Linux 2.6.21)
• Fedora Core 6 (i386, amd64, ppc using gcc 4.1.1 and glibc 2.5 at Linux 2.6.20)
• Red Hat Enterprise Linux 5 (i386, amd64, ppc using gcc 4.1.1 and glibc 2.5 at Linux 2.6.18)
• Red Hat Enterprise Linux 4 (i386, amd64, ppc using gcc 3.4.3 and glibc 2.3.4 at Linux 2.6.9)

We were informed that the all of these pass the testsuite. Fedora 7 quality assurance is being run on it until approximately this weekend; to install mksh, simply type yum install mksh (for RHEL, you'll have to enable the EPEL repository first).

The Fink package manager for Mac OSX now also contains mksh R29f.
