+Description: use pkg-config (via ExtUtils::PkgConfig) instead of the removed gdlib-config.
+ Additionally remove parts from try_to_autoconfigure which are not needed, at least on Debian,
+ and adjust some variable to the different output of pkg-config.
+ pkg-config doesn't return "features", so we're hardcoding it for now, taken from gdlib-config
+ as of src:libgd2 2.2.3-1.1 (rebuilt with gdlib-config re-enabled).
+ .
+ This patch might need more massaging before upstreaming it wrt non-Debian systems,
+ and inclusion of ExtUtils::PkgConfig into the distributions metadata.
