Dave, getting a new wx assert on launching 3.3.1608
compiled with clang on osx 10.7.5 using make & against wx 2.9.5.
the only line of interest in O's log was.....
Warning: WMM model data file /Users/mo/OpenCPN/build/plugins/WMM.COF can't be loaded, using the bundled data.
there is still an issue with the wmm plugins final resting place when o compiles, wmm_pi and also Climatology_pi do not get placed in the correct folder - OpenCPN

Btw which is the recommend version of WX for the current
Here's a screen
shot of the assert....
