I've built and installed NetBSD/amd64 -current (3.99.3; should be up-to-date
userland and kernel as of a few days ago) and freshly installed on a disk
that previously had NetBSD/i386 on it.  (So there should be nothing "old"
or "obsolete" lying about; (^&.)

One of several packages that i wanted to build for the new installation
was povray, from pkgsrc.  Attempting to do so fails with this error:

 /~~~ error from build

 \___ error from build

Attempting to resume the build seems to consistantly reproduce this error.

Should I send a toolchain PR?  Or post to -current?  (Can someone else
confirm?)

Other than "try to build povray", I have no way to reproduce this error at
this time.  The povray version is 3.6.1, PKGREVISION 1.
