 system, just set the environment variable GEOS_DIR to point to the location 
 of libgeos_c and geos_c.h (if libgeos_c is in /usr/local/lib and
 geos_c.h is in /usr/local/include, set GEOS_DIR to /usr/local).
 Then go to step (3).  If you don't have it, you can build it from
 the source code included with basemap by following these steps:
 
+```
  > cd geos-3.3.3
  > export GEOS_DIR=<where you want the libs and headers to go>
    A reasonable choice on a Unix-like system is /usr/local, or
    if you don't have permission to write there, your home directory.
  > ./configure --prefix=$GEOS_DIR 
  > make; make install
