 7 - VECTOR DIGITIZER
 
 To enable digitizer you need to compile 'vdigit'
 component. Note that you must configure GRASS with C++ (--with-cxx),
 Python (--with-python) and wxWidgets (--with-wxwidgets) support.
 
-NOTE: There is no need to do the following symlink or ldconfig on OSX.

 First, create a symlink to _gdi_.so shared library
 
-$ sudo ln -s `locate _gdi_.so` /usr/local/lib/libgdi.so
+- find out architecture (32 or 64bit):
+   $ echo "$HOSTTYPE"
 
-e.g.
+- find the _gdi_.so file and check if compliant:
+   $ locate _gdi_.so
+   $ file /path/to/_gdi_.so
 
-$ sudo ln -s /usr/lib/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/_gdi_.so /usr/local/lib/libgdi.so
+  It will report "ELF 32-bit..." or "ELF 64-bit..". If you have
+  multiple results with locate, link below the appropriate file.
 
+- link as library:
+   $ sudo ln -s /path/to/_gdi_.so /usr/local/lib/libgdi.so
+
+  e.g.
+   $ sudo ln -s /usr/lib64/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/_gdi_.so /usr/local/lib/libgdi.so
+
 Then update LD_LIBRARY_PATH or add '/usr/local/lib' to /etc/ld.so.conf
 (in this case run 'sudo ldconfig').

 Then you can compile the driver

 $ make
