Hi William,

Thanks for help.

I found I did not need to specify these. I didn't have issues with
spatialindex not being found (once it was installed in /usr/local). Seems
cmake/FindSpatialindex.cmake has 'PATH_SUFFIXES spatialindex' already to
aid in that. Note: I installed from spatialindex-src-1.7.1.

Once found, I see another problem - internally, spatialindex headers

Yes, this worked. It was the only edit needed to build successfully.

Does this mean libspatialindex.dylib will need to be added to
QGIS.app/Contents/MacOS/lib and linking updated for successful app
bundling, as well?


The built app is useable, but I'm still getting two crashes, under Lion
(haven't tested on Snow Leopard, yet):

1) The networking issue is still crashing on any call to external resources
[0][1].

Typing the following into PyQGIS Console causes an immediate crash:

 from PyQt4.QtWebKit import QWebView from PyQt4.QtCore import QUrl

webviewer = QWebView()

webviewer.setUrl(QUrl("http://www.qgis.org"))

2) Crashes on quit, regardless of having worked in it a while or only
having launched it.

Do you have these issues with your builds?
