I'm not exactly sure what you're looking for, but maybe try this:
(interactively)
sage: import os
sage: os.uname()
('Darwin',
'Macintosh.local',
'9.7.0',
'Darwin Kernel Version 9.7.0: Tue Mar 31 22:52:17 PDT 2009;
root:xnu-1228.12.14~1/RELEASE_I386',
'i386')
os.environ and os.system('ld --version') might also be helpful. In a
python file:
import os
sysname = os.uname()[0]
ld_version = (something involving os.system('ld --version'))
if sysname == 'Darwin' and ld_version == blahblahblah:
print "hello, this is Darwin"
elif sysname == 'Solaris': # I don't really know what the right thing
is for sysname here
print "solaris"
else:
print "other system"
See <http://docs.python.org/library/os.html> for more on the Python os
module.
