Comment (by nbruin):
Looking at the implementation of sage.misc.sage_ostools.have_program, we
might want to change:
{{{#!diff
- if os.access(os.path.join(p, program), os.X_OK):
+ pth=os.path.join(p, program)
+ if os.isfile(pth) and os.access(pth, os.X_OK):
}}}
since `os.access(..., os.X_OK)` might return true for a directory and yet
this would not be picked up as an executable by the operating system.
