R 2.5.1 compiled, passed the make check and has been successfully running
for a couple years on a Sun Fire V490 running Solaris 9. I need a newer
version of R, but can't get a newer version of R to pass the make check.
I've tried 2.8.1, 2.7.2, 2.6.2 and 2.6.0. (2.5.1 still passes on this
server) At this point I thought I'd try to compile it on another Sun server
(Solaris 10), but it had the same problem. Configuring with no options
didn't help. I commented out the failed test from the Makefile to see if it
would pass the rest of the tests. It passes all the rest of the tests. Here
is the failure error from make check.

running regression tests

Here is output from reg-tests-1.Rout.fail.

Error: unlink("dir?") == 1 is not TRUE

Looking through the archives I did find a couple other people with this
error, both running Solaris 10. PR#10501 and PR#11738 have quite a lot of
information about this error, but I don't see any resolution for them.

This looks like it could possibly be enough of a problem that I haven't put
2.8.1 in production. Can you help me with a resolution or let me know if it
is safe to ignore? I'd appreciate it.

Thank you!
Karen
