+Unresolved Installation Problem on OSX 10.6
+-------------------------------------------
+When installing on some instances of OSX 10.6, a few users have noted a failure
+when yt tries to build with OpenMP support:
+
+    Symbol not found: _GOMP_barrier
+        Referenced from: <YT_DEST>/src/yt-hg/yt/utilities/lib/grid_traversal.so
+
+        Expected in: dynamic lookup
+
+To resolve this, please make a symbolic link:
+
+.. code-block:: bash
+
+  $ ln -s /usr/local/lib/x86_64 <YT_DEST>/lib64
+
+where ``<YT_DEST>`` is replaced by the path to the root of the directory
+containing the yt install, which will usually be ``yt-<arch>``. After doing so, 
+you should be able to cd to <YT_DEST>/src/yt-hg and run:
+
+.. code-block:: bash
+
+  $ python setup.py install
+
+
+
 How do I cite yt?

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
