You should not have ":" on the second line. ":" separates arguments and both
properties above are part of the 'requirements' argument.

Uhm, try this:

 exe a : a.cpp
         : <cflags>"`pkg-config --cflags glib-2.0`"
           <linkflags>"`pkg-config --libs glib-2.0`"
     ;

or

 exe a : a.cpp
         : "<cflags>pkg-config --cflags glib-2.0"
           "<linkflags>"`pkg-config --libs glib-2.0"
     ;

or:

                local x = [ SHELL "pkg-config --cflags glib-2.0" ] ;
        # Strip newline
        local y = [ MATCH "(.*)[\n]" : $(x) ] ;

        exe a : a.cpp : <cflags>$(y) ;

As you see, while I know a good deal of possible solutions, I don't
necessary test them all :-)
