Hi Evan,
Thanks! That solution works, but I also had to add a link for libjvm.dylib.
In: /usr/local/lib
I added links (sudo ln -s):
libjava.dylib@ -> /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/libjava.dylib
libjvm.dylib@ -> /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/server/libjvm.dylib
And now import orekit works… The "The Basics" and "TLE Propagation" ipython notebooks both run ok so I think I'm business.
It's not the cleanest solution since it's tied to that particular jdk, but it works for now. (I'm not sure, but adding .../jre/lib and .../jre/lib/server to PATH should also work, unless there is something significant about having dylib links in /usr/local/lib?)
Now I'm just fetching basemap so I can run the "orekit map" notebook example…. (a few millicentons pass…) Success - it works too.
Cheers,
- Mike Corvin

Hi Mike,
I ran in to this issue before, but I'm trying to remember how I solved it. I think I ended up adding a sym link from /usr/local/lib (or the Mac equivalent) to libjava.dylib. For some reason the java runtime library isn't on the library path by default in Mac.
Hope it helps,
Evan

Bonne Année!
While trying to import orekit in Python on my Mac I'm getting a "Library not loaded: @rpath/libjava.dylib" error.
I'm running on OSX 10.8.5 and Anaconda Python. I've set JAVA_HOME and PATH to point at a fairly recent Java 1.7. I used the
conda install commands to get jcc and orekit 7, both of which appeared to install without error and are in the
conda list. The orekit-7.0.jar and the commons-math jar are in the site packages under in the anaconda directories.
Here is my Java environment:
~ > echo $PATH
/Users/zwork/anaconda/bin:/opt/subversion/bin:/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin:/Users/zwork/bin:.:/Applications/Julia-0.3.2.app/Contents/Resources/julia/bin:~/Applications/PlantUML
~ > echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
~ > find $JAVA_HOME -name libjava.dylib
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/libjava.dylib

And here is the import error in Python:

The same error occurs when trying to import the jcc package by itself. The error also occurred with the environment configured to point at the (old) default Java 1.6 in /System/Library (but that version did not appear to have a libjava.dylib).
Do I need to export a JCC_JDK environment variable and additional path items similar to what is indicated for Windows installations?
I have been using Orekit 1.6 from Matlab very successfully, but want to transition my implementations to Python (and Julia!).
Thanks for any suggestions/hints/fixes!
