# run as: ./makegs2.sh [gnome-lib] [imagemagick]
# If gnome-lib passed in, will compile GS2 using gnome-lib 
# which checks out gnome-lib src from svn if possible and if needed (if no ext/gnome-lib-minimal)
# If you pass in imagemagick, it will grab the appropriate linux/darwin binary, untar
# this and put its OS subfolder renamed as imagemagick into the bin/os folder.

# Note, Mac (darwin) machines don't always display all env vars on doing env/printenv, 
# e.g. DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH are hidden
# To display hidden vars follow:
# http://www.commandlinefu.com/commands/view/6899/print-all-environment-variables-including-hidden-ones
# but remove capital T from command, making: for _a in {A..Z} {a..z};do _z=\${!${_a}*};for _i in `eval echo "${_z}"`;do echo -e "$_i: ${!_i}";done;done|cat -Tsv
# into: for _a in {A..Z} {a..z};do _z=\${!${_a}*};for _i in `eval echo "${_z}"`;do echo -e "$_i: ${!_i}";done;done|cat -sv
# Can redirect the output of the command into files and do a diff to see difference in environment.
