Afraid I've got to go along with cudak888's verdict. I closed a deal on another slightly earlier Voyager frame with the same problem. The guy selling it was honest enough to mention the seat post when he discovered it (the stem was mentioned in the sale), took a day to try and get the seatpost out, sent me back my money. Real honest guy, will happily deal with him again. By the way, I bought it for $39.00 and change, including shipping.
Damned shame - I had one of the opaque blue ones when they were called World Voyagers, was a 15-speed, all top of the line Shimano except brakes, put fenders on it and a couple of carriers and went all over hell's half acre with it.
