I was trying to build Sage for the first time and I ran into some errors. The 
first few I could fix (mismatched gcc/g++/gfortran versions) but after the 
initial errors were fixed the installer seemed to be chugging along just fine. 
About 3-4 hours in the process failed, though, on conway_polynomials. I've 
appended the log file below; I'm not sure what more to say since this has my 
system details.

Found package conway_polynomials-0.4.p0 in 
spkg/standard/conway_polynomials-0.4.p0.spkg

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the relevant part of the log file
  /home/charles/mth/sage-5.13/logs/pkgs/conway_polynomials-0.4.p0.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/home/charles/mth/sage-5.13/spkg/build/conway_polynomials-0.4.p0 and type 
'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd '/home/charles/mth/sage-5.13/spkg/build/conway_polynomials-0.4.p0' && 
'/home/charles/mth/sage-5.13/sage' --sh)
When you are done debugging, you can type "exit" to leave the subshell.
