Hi Dave,<div><br class="webkit-block-placeholder"></div><div>Thanks for the info. I'm forwarding your message to the tioga-users list since it may be of wider interest.</div><div><br class="webkit-block-placeholder"></div><div>Sorry about the Mac rubygems problem -- I'm glad you were able to work around it.</div><div><br class="webkit-block-placeholder"></div><div>Concerning NArray -- we are currently going through a reworking of the tioga implementation prompted by Taro Sato's project to make a Python version. Taro's version of tioga doesn't use Dvectors -- it uses the standard python analog of NArray.</div><div><br class="webkit-block-placeholder"></div><div>So, if you're willing to help Taro get some new software working, you might want to give "PyTioga" a try!</div><div>Here are the links: <a href="http://pytioga.sourceforge.net">http://pytioga.sourceforge.net</a>/ and <a href="http://sourceforge.net/projects/pytioga">http://sourceforge.net/projects/pytioga</a></div><div><br class="webkit-block-placeholder"></div><div>For the ruby Tioga, the NArray to Array to Dvector hack is probably the best work around for the short term.</div><div><br class="webkit-block-placeholder"></div><div>Cheers,</div><div>Bill</div><div><br class="webkit-block-placeholder"></div><div><br class="webkit-block-placeholder"></div><div><br><div><div>Begin forwarded message:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="margin-top: 0px;
