On the Skynet hosts flavius (x86_64-Linux-k8-f12), iras (ia64-Linux-suse),
installing the Python package sometimes fails with
{{{
[...]
Sleeping for three seconds before testing python
'import site' failed; use -v for traceback
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named math
math module failed to import
}}}
This is with 4.6.alpha2. Running `./sage -python` and doing `import math`
works.
From near the end of `spkg-install`:
{{{
#!sh
[...]
# Sleeping for three seconds so that parallel 'make install' catches up
# with the following test.
echo "Sleeping for three seconds before testing python"
sleep 3
# Make sure extension modules were built correctly.
python -c "import math"
if [ $? -eq 0 -a -f "$SAGE_LOCAL/bin/python" ]; then
echo "math module OK"
else
echo "math module failed to import"
exit 1
fi
[...]
}}}

Comment(by mpatel):
Logs are [http://sage.math.washington.edu/home/mpatel/trac/10082 here].
Actually, the error on menas (x86_64-Linux-core2-suse) is different:
