[Etoys] Ogg Vorbis and Speex CODEC for Squeak eToys

[Bert Freudenberg]

Takashi,

you need to make sure the VM compiles even without the headers and  
libraries present. We need to have configure-time checks for all  
needed headers and libraries, and disable the plugin if those are not  
present. I see you check for the headers, but not for the libraries.  
There is an AC_PLUGIN_CHECK_LIB macro for this, see doc/ 
HowToBuildFromSource.txt

The proper way to make sure ogg or speex is installed would be in  
sugar-jhbuild sanitycheck.

Also, we might add a configure switch that makes certain plugins  
mandatory, so configure fails if it does not detect the prerequisites  
to mandatory plugins. Ian, do you have an idea how to best implement  
this?
