The simplest way is to do something like this:

#!python
# use GTK
CCFLAGS = ' `pkg-config --cflags gtk+-2.0` '
LINKFLAGS = ' `pkg-config --libs gtk+-2.0` '

env = Environment(CCFLAGS=CCFLAGS, LINKFLAGS=LINKFLAGS)
env.Program('toaster-test.c')

Remember to keep them separate, you cannot do what you do in makefiles and specify --cflags and --libs together.

However, the cleaner, more correct - and really not much harder - way is to use ParseConfig like so:

#!python
env = Environment()

# add support for GTK
env.ParseConfig('pkg-config --cflags --libs gtk+-2.0')

env.Program('toaster-test.c')

Of course, the above steps assume pkg-config and GTK+ are installed (though they will almost always be). If you want your configuration to be able to check for the existence of pkg-config, use something like what follows:

#!python
env = Environment()

def CheckPKGConfig(context, version):
     context.Message( 'Checking for pkg-config... ' )
     ret = context.TryAction('pkg-config --atleast-pkgconfig-version=%s' % version)[0]
     context.Result( ret )
     return ret

def CheckPKG(context, name):
     context.Message( 'Checking for %s... ' % name )
     ret = context.TryAction('pkg-config --exists \'%s\'' % name)[0]
     context.Result( ret )
     return ret

# Configuration:

conf = Configure(env, custom_tests = { 'CheckPKGConfig' : CheckPKGConfig,
                                       'CheckPKG' : CheckPKG })

if not conf.CheckPKGConfig('0.15.0'):
     print 'pkg-config >= 0.15.0 not found.'
     Exit(1)

if not conf.CheckPKG('gtk+-2.0 >= 2.4.9'):
     print 'GTK+-2.0 >= 2.4.9 not found.'
     Exit(1)

# Your extra checks here

env = conf.Finish()

# Now, build:

env.ParseConfig('pkg-config --cflags --libs gtk+-2.0')

env.Program('toaster-test.c')
