system popt

[Matthias Clasen]

Hey, I built 0.24 in Fedora and tried to switch to using system
libraries. Using system glib is fine, but when using system popt, 
I get errors like the following:

checking for GCALCTOOL... configure: error: Package requirements (
    gtk+-2.0 >= 2.18
    gconf-2.0 >= 1.1.9
    gio-2.0
    libxml-2.0
    gmodule-export-2.0
) were not met:
Couldn't parse Cflags field into an argument vector: missing argument
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GCALCTOOL_CFLAGS
and GCALCTOOL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.


So I had to switch back to using the included popt for now.
