[gentoo-user] Not able to install ksh93

[Harry Putnam]

I've been running ksh93 on this newish install of gentoo for a couple
of months and have done several full emerge -vuD world successfully.

But 2 days ago, attempting a full update (emerge -vuD world) I find
ksh93 package fails... My unsophisticated look at the output which is
posted in full here ( zeus.jtan.com/~reader/vutxt/disp.cgi ) seems to
indicate that the package tries to install `nmake', but fails.  Then
continues on with piles of output ending finally with a failure,
(unsurprisingly) to find `nmake'. (That snippet of output is inlined at
the end).

I didn't have sense enough to capture the initial output that started
this but moved right into what I thought might be a solution
... unmerging ksh, then installing an older version. (Thinking the
error was being caused by something new in the latest ksh)

It still seems that something new or different must have happened
since ksh was installed and running befor the update.

So the output included here is from an attempt to install an older
version (ksh-93.20110208). (again, full output is available here:
zeus.jtan.com/~reader/vutxt/disp.cgi)

Hopefully someone here will recognize what is happening and some idea
what I should do about it.
