Try running pptpclient-1.80. Configuring done and running on terminal.
# pppd call freevpn (/etc/ppp/peers/freevpn)
To see where is my connection is ?.
# route
And route all my connection trough ppp0.
# route add default dev ppp0
And i can't surf to internet, so i check my configuration again.
But I found files at /etc/ppp named by connect-errors and see what I found...
This files is log from /usr/bin/pptp.
....
sh: /bin/ip: not found
sh: /bin/ip: not found
sh: /bin/ip: not found

sh: /bin/ip: not found
sh: /bin/ip: not found

So I check running on terminal.
