Comment (by vince):

 Thanks for that quick answer.

 Replying to [comment:1 kyngchaos]:
 > Works fine in the Xcode project build.  locale_charset() is a part of
 the iconv in OS X.  Maybe there are variations of libiconv (OSX uses GNU
 iconv) and you're using a different one than provided by Apple that uses
 the linux method?  In any case, this is really an issue with spatialite,
 and is not something that can be fixed in Qgis.

 Ok. MacPorts uses its own libiconv. That's why the link fails. I tried to
 link against system libiconv, but it raises other errors, so the patch is
 fine and justified (adapt a build to Macports).

 > Qgis detects Python from your PATH, so add your prefered python bin
 folder to the front of your PATH before configuring.  Also, Qgis uses an
 internal python interpreter and links directly to the python framework, so
 it happens at linking and you can't change it at runtime.

 Okay, so let me put it another way: I have two Python frameworks. One is
 the Apple default, the other is the new 2.6.2 Python release compiled
 under Macports and located elsewhere. How can I force Qgis to link with
 the latter rather than the former?

 > Qgis uses the GRASS libraries directly, not thru GDAL.  Maybe it's not
 autodetecting GRASS?  On OSX, cmake defaults to looking for an application
 build of GRASS in a default install path, so if you have a Unix build or
 have customized the install location, you must specify the
 GRASS_INCLUDE_DIR and GRASS_PREFIX when configuring Qgis.

 That's what I did, and it is fine:

 but it does not seem to show up in the extensions. The libqgisgrass.dylib
 are present, BTW.
