Hi all,

I can confirm that this works perfectly with a small change:

> +CONFIGURE_ARGS +=	-DNO_DOCS=ON \
> +			-DUSE_WEBENGINE=OFF \
> +			-DFBSUPPORT=OFF \
> +			-DBTSUPPORT=OFF \
> +			-DNO_PRINTING=ON \
> +			-DNO_USERMANUAL=ON

The NO_DOCS, FBSUPPORT, and USE_WEBENGINE are not necessary: the first 
two do not exist and the last is implied by no printing or usermanual. 
I've attached a patch (following yours) that has those removed.

Thank you again Rafael and Stuart!  This tool is so useful to me--I 
really appreciate your help.

Best,

Kristaps
