[R-pkg-devel] Finding/specifying Installation path of gdal in a travis-ci build

[Benjamin Leutner]

Hi,

I can't speak for gdalUtils, but my package uses rgdal and builds well 
on travis.
I'm also installing gdal-bin, which you are not. Maybe that helps.
Here's my (admittedly somewhat messy) travis file:
https://github.com/bleutner/RStoolbox/blob/master/.travis.yml

Cheers,
Benjamin
