>Description:


x11/gtk2 uses "gtk2+" as package name. Using multiple options
for gtk2, e.g. using the "cups" option and the automatically
added "x11" option leads to the following error when trying to
build depending packages:

# make: don't know how to make x11. Stop

Here an excerpt from a build of www/firefox with the make
command called by install-dependecies echoed to the tty
before executing it:

obviously, the "PKG_BUILD_OPTIONS.gtk2+=cups\ x11" in the call is
responsible for the problem. Removing e.g. the "cups" option for
gtk2+ (e.g. in mk.conf) allows for continuing the build but is obviously
not a fix.





>How-To-Repeat:


set PKG_OPTIONS.gtk2+ to "cups" in mk.conf and try to build a
package that depends on gtk2+.


>Fix:


Using a "+" in a package name is obviously not a good idea, as
make variable names are derived from it. In order to use the
"+=" syntax to add a value to the list, one has to add an additional
blank that is not necessary for normal variables. 

Therefore the easiest way would be to disallow "+" in packages. 
The real cause seems to be makes command line parsing of
variable assignments containing a "+" in their name.
