Greetings,

I wonder how can we include conditional buildlinking for problems  
like the once described in pkg/35358 ("pkgsrc/www/curl/buitlin.mk" is  
broken), where built-in curl may or may not be linked against libidn.  
I would like to have libidn optionally buildlinked, depending on the  
output from 'curl-config --features'.

Please, advice.

Kind regards,
Adam
