Comment(by jhpalmieri):
Or perhaps this patch to the script sage-notebook:
{{{
#!diff
diff --git a/sage-notebook b/sage-notebook
--- a/sage-notebook
+++ b/sage-notebook
@@ -2,6 +2,13 @@
import os, sys, socket
+CUR=os.path.abspath(os.curdir)
+if os.path.samefile(CUR, os.path.join(os.environ['SAGE_ROOT'], 'devel',
'sage')):
+ try:
+ sys.path.remove(CUR)
+ except ValueError:
+ pass
+
print open(os.environ['SAGE_ROOT'] + '/local/bin/sage-banner').read()
print "Please wait while the Sage Notebook server starts..."
}}}
This looks safer than my first suggestion, although it could be a bit more
refined: search sys.path not just for CUR, but for anything which is
equivalent to CUR.
