development packages from pkgsrc

[H Xu <xusubsc%gmail.com@localhost>]

Hello,

Does pkgsrc provide any devlopment packages(including headers, link 
libraries, etc.) for python, sqlite, etc? When I want to build something 
depending on libraries other than the standard library, I found it I 
always need to download the source package from the official website.

Any ideas?

Thanks.
