i'd call for three reasons...

1) there have been a decent amount of exposed clubs already out, so a flush seems a tad less likely.

2) if he did have a flush and hit a four flush on 4th, would he play his hand harder by trying to jam?

3) when he hit the flush, why didn't he go for the checkraise?

these factors lead me to think more towards calling than folding, though i wouldn't really like it.
