Ah!  DRAM / swap is probably the issue.  I'm working on a TS-7300  
from EmbeddedArm < http://www.embeddedarm.com/epc/ts7300-spec-h.htm

compilation I did was without swap space.

THe best alternative is probably getting a XC environment up and  
running - e.g. OpenEmbedded, ScratchBox, buildroot, or just plain old  
Crosstools.  From what I hear on other lists, the first is generally  
considered "the best" (I have no experience with any of them).

I also remember OE flying around on this list a while back.  Did  
anyone successfully get GNU Radio compiling in OE?  There was some  
talk about FFTW not being available or something ... was that the  
primary issue? - MLD
