If you look at the source for the function, it checks the "SAS_host" 
against a known list, containing

# Host systems known to work
KNOWNHOST <- c("WIN_PRO", "WIN_NT", "WIN_NTSV", "WIN_SRV",
                "WIN_ASRV", "XP_PRO", "XP_HOME", "NET_ASRV",
                "NET_DSRV", "NET_SRV", "WIN_98", "W32_VSPR",
                "WIN", "WIN_95", "X64_VSPR", "X64_ESRV")

Praveen's host is not in that list, so the package author has never 
tested it.   But nothing else in the code appears to depend on the host, 
so it's a good guess that adding another host string to that list (or 
changing the error to a warning) will make it work properly.
