The answer to this problem is in the FAQ
http://www.vibrationresearch.com/pptpd/pptpd-FAQ.txt:

7.4.1.	Get PPP_VERSION or PPP_MAGIC undefined error message while compiling
ppp kernel modules

	Solution: add the following lines to
/usr/src/linux/include/linux/if_ppp.h
		#define PPP_VERSION "2.3.11"
		#define PPP_MAGIC   0x5002  /* Magic value for the ppp
structure */

I'm not a big fan of telling people to RTFM, but sometimes it doesn't hurt.
Also, I found similiar documentation by simply searching for "ppp_magic
poptop" at http://www.hotbot.com.
