mysql5, mysql5-server, inkscape are built from source

[Davide Liessi]

Hi all.

I am upgrading mysql5 and mysql5-server from 5.1.68_0 to 5.1.70_0.
I noticed that MacPorts is building them from source.
Since I am on Snow Leopard with default configuration and using
default variants, I thought MacPorts would download a prebuilt
archive.
Is this expected?

Also, if I remember correctly, inkscape has always been built from source.
Why isn't there a prebuilt package?

Thanks in advance.
Best regards.
Davide
