about precompiled binaries of pkgsrc for arm64 netbsd

[Alejandro Sánchez Marín <erchache2000%gmail.com@localhost>]

Hello, I'm installing Netbsd 8 on my pinebook.

I'm using pkgsrc from source because don't exist precompiled binaries 
for arm64 on this version. I see lastest binaries was from 6.1.

Why or How we can't get precompiled binaries for arm64? My machine is 
too slow and system isn't configured to get all the hardware power to 
fast build compilation.

It's a horrible user n00b experience to trying to get a functional 
machine with netbsd.

What we need to get this packages right now? Hardware, hosting, housing, 
money, beer, drugs, sex, rock'n'roll...? ;(

I'm waiting for your replies.

Thanks in advance for wasting your patiente and time with this n00b user.
