The usual would be "import salvus". Is your issue that this command may
fail if MEGUA_PLATFORM!='sagews'?
You could just put the "import salvus" line directly above
"salvus.file(...)". That only has a slight runtime penalty for being
executed multiple times.
If that penalty is too high (I doubt it would be), you can just do the
import one time, guarded by an "if":
if MEGUA_PLATFORM=='sagews':
import salvus
