I'm having trouble getting Myth to compile on my MacMini1.1 (mid

I run the command "sudo port install mythtv-core.25." All goes
well until the script tries to install myth itself, then it stops
with the message:

I've attached the log. Any suggestions?
The error in the log is:

It looks like this assembly-language code is not compatible with the
processor in your Mac mini. Specifically it looks like the code is
trying to use more processor registers than your processor has
available. That's according to this page I found with a quick search:
http://stackoverflow.com/questions/8275859/error-cant-find-a-register-in-class-general-regs-while-reloading-asm
Only the first series of Intel Macs used the 32-bit Core processor;
all the others use 64-bit processors, and 64-bit Intel processors
have a lot more registers.
You should report this problem to the developers of mythtv so they can fix it.
A solution might be to tell mythtv to not use assembly code. I'm not
sure what configure arguments might need to be added to do that.
Thanks for digging that up, Ryan. I know there is a configure flag
to not use Yasm--but I think these are in-line assembler commands.
I'll have to check if/how to disable.
In case I need to, how does one check the specific processor model in
the portfile? Could you point me to some sample code?
