<br><br>Hi Chrystal,<br>
<br>
It is possible that you have discovered a bug. There is not a<br>
dashboard build for Mac 10.7/GCC. There is a Mac 10.7/Clang build:<br>
<br>
<a href="http://open.cdash.org/viewNotes.php?buildid=3171172" target="_blank">http://open.cdash.org/viewNotes.php?buildid=3171172</a><br>
<br>
It may be worthwhile to try first see that it works.<br>
<br>
Thanks,<br>
Matt<br>
