Thanks for your prompt reply ...

When we execute make command after that what I get is

bash-2.03# make
sh: /0: not found
*** Error code 1
make: Fatal error: Command failed for target `blib/lib/Net/.exists'


bash-2.03# find / -name sh
/usr/lib/mail/sh
/usr/bin/sh
/usr/xpg4/bin/sh

So i also searched for sh.
