DSSS install of gdc-gcc-4.1 fails on OS X

[Steven Grimm]

Following the advice in the tutorial videos on the DSSS page, I ran 
"dsss net install gdc-gcc-4.1" to get a fresh install of gdc on my 
machine. It downloaded and compiled a bunch of stuff, but then errored out:

MLIBS=`/private/tmp/DSSS_gdc-gcc-4.1/4.1/gcc-4.1.2/build/./gcc/xgcc

Is this a known issue on OS X? Is installing gdc using DSSS only 
supported under Linux? If this problem is something new, I'll be happy 
to provide any information that'll help diagnose the problem; just let 
me know what's useful.

Also, I note with some suspicion that it thinks it's building for the 
i386 architecture, when in fact it should be i686 -- probably not a huge 
difference but I assume the i686 target would generate different code to 
take advantage of new instructions, etc. I'm happy to live with i386 for 
now if I can get it to work at all.

I had previously downloaded an OS X installer for gdc, which worked (and 
is how I got a DSSS binary) but it installed itself in /usr and I'd 
rather install in a user account for now so I can easily package up the 
environment and copy it to other machines.

Thanks for any advice anyone can give me!
