R-beta: R-0.50-a4 library problem (survival4)

[U-E59264-Osman Buyukisik]

I have built R-0.50-a4 on HP9000/C160-hpux10.2 with gcc (cc for
libs). When I try 
library(survival4)
Error in pos.to.env(pos) : invalid "pos" argument

And it does not load. Other libs seem to work. I tested integrate (has
f2c translated c), polynomial.

Is this a problem with my system only???
TIA
osman
