[R] problem building R on HPUX 11.23

[Charles F. Fisher]

When building the X11 modules under HPUX 11.23 I get the following errors

ld: Unsatisfied symbol "Rf_isNull" in file dataentry.lo
ld: Unsatisfied symbol "Rf_length" in file dataentry.lo
ld: Unsatisfied symbol "Rf_warningcall" in file devX11.lo
ld: Unsatisfied symbol "UNIMPLEMENTED" in file dataentry.lo
ld: Unsatisfied symbol "R_alloc" in file devX11.lo
ld: Unsatisfied symbol "R_GlobalEnv" in file dataentry.lo
ld: Unsatisfied symbol "R_setX11Routines" in file devX11.lo
ld: Unsatisfied symbol "Rf_devNumber" in file devX11.lo
ld: Unsatisfied symbol "Rf_elt" in file devX11.lo
ld: Unsatisfied symbol "R_NaInt" in file dataentry.lo

I assume I need to link in an R library built earlier; which library would 
I need?

Please reply directly, as I am not on the list.

Thanks
