[Goptical] installation on Mac OSX 10.9

[Achim Franz]

Hello, 

I'm trying to install the goptical package on my Mac running OSX 10.9. after 
running ./configuration I first get stuck by two calls to 'sleep()' in two of 
the example files:

test_rendering.cc:200:3: error: use of undeclared identifier 'sleep'

goptical_core/tests/test_2d_plot.cc:  sleep(5);
goptical_core/tests/test_rendering.cc:  sleep(5);

when I comment these lines out it compiles. Next step is 'make install' which 
lists towards the end:

test -z "/usr/local/share/info" || /sw/bin/gmkdir -p "/usr/local/share/info"
 /sw/bin/ginstall -c -m 644 ./goptical.info ./goptical.info-1 ./goptical.info-2 
'/usr/local/share/info'
 install-info --info-dir='/usr/local/share/info' 
'/usr/local/share/info/goptical.info'
install-info(/usr/local/share/info/goptical.info): warning, ignoring confusing 
INFO-DIR-ENTRY in file.

No `START-INFO-DIR-ENTRY' and no `This file documents'.
install-info(/usr/local/share/info/goptical.info): unable to determine 
description for `dir' entry - giving up

as I assume that is just the documentation, so I tried running the examples:

[franz:goptical-1.0/examples/curve_model] root# ./usercurve 
   [1]N9_Goptical3Sys11SourcePointE at [0, 0, -1e+09]
   [2]N9_Goptical3Sys6MirrorE at [0, 0, 1500] N9_Goptical8Material5ProxyE 
N9_Goptical8Material6MirrorE
   [3]N9_Goptical3Sys5ImageE at [1.05966e-15, -4.5116e-15, 0.572886]


[franz:goptical-1.0/examples/curve_model] root# 


it just runs through and produces a svg file, I assume that is the result. I'll 
try and get my own setup going. If all this sounds familiar let me know, at 
least that way I know I'm not missing something.

Thanks
Achim
