#3990: ST_AsMVTGeom fails on OS X (and Heroku)
----------------------+---------------------------
 Reporter:  tyrauber  |      Owner:  pramsey

 ST_AsMVT and ST_AsMVTGeom look like good additions to PostGis.
 Unfortunately, ST_AsMVTGeom fails on both OSX and heroku.

 On OS X I upgraded postgres and postgis using brew and installed
 protobuf-c.

 Running the documentation query:

 {{{
 SELECT ST_AsMVT(q, 'test', 4096, 'geom') FROM (SELECT 1 AS c1,
     ST_AsMVTGeom(ST_GeomFromText('POLYGON ((35 10, 45 45, 15 40, 10 20, 35
 10), (20 30, 35 35, 30 20, 20 30))'),
     ST_MakeBox2D(ST_Point(0, 0), ST_Point(4096, 4096)), 4096, 0, false) AS
 geom) AS q;
 }}}


 Results in the error.

 ERROR:  Missing libprotobuf-c

 The same error is seen on Heroku.
