[petsc-dev] funny error on osx

[Satish Balay]

If you are mssing with dns - try the following.

1. check your hostname

2. make sure you have an entry for this name in /etc/hosts file.
[It works for linux - and I think it should work for Mac aswell.]

For eg:

balay at asterix /home/balay
$ hostname
asterix
balay at asterix /home/balay
$ grep asterix /etc/hosts
127.0.0.1   asterix localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         asterix localhost localhost.localdomain localhost6 localhost6.localdomain6
balay at asterix /home/balay
$
