the maple interface is broken in some configurations #1465
Description
G Edgar reported that on his mac the maple interface fails miserably to work at all.
On sage.math it works perfectly. On my laptop (osx10.5.1 w/ maple 11) it does NOT work now.
On my laptop:
sage: maple.eval('2+2')
'read "/Users/was/.sage//temp/D_69_91_158_192.dhcp4.washington.edu/10242//i'
