Latest release was 1.1.0-1 on March 20th 2002:

Version 1.1.0 of pptp-linux removed the dependency on ppp-mppe, since many users do not need MPPE to use PPTP Client. However, if your PPTP Server requires MPPE, use a ppp-mppe package from the prior release below, or obtain an MPPE capable kernel from {http,ftp}://planetmirror.com/pub/mppe/.

Prior release was on May 7th 2001:

Version 1.0.3 of pptp-linux adds support for drop-in site specific config files that contain all the configuration needed to setup a tunnel. You can find an example site specific file here. These files live in /etc/pptp.d/.

RPMs for 1.0.3 were built on Red Hat 6.2 with updates applied. They should work correctly on updated 6.2 as well as updated 7.0, ppp-mppe includes kernel modules for 2.2.19 on both versions on both architectures. If you use a different version, feel free to try to build the src.rpm.
