There is not sufficient information to go on here (with a sun.com 
address you could be expected to know better). R works fine as a 64 bit 
program on several platforms, as far as I know including Solaris, so the 
issue has to be specific to your compiler and library setup.

This has all the hallmarks of a math header file error (either args or 
return value declared of the wrong type), or a linker issue (log not 
really log). I surely hope it fails "make check"!

So, exactly what did you do, which compiler and build tools and which 
version?
Did you read the http://cran.r-project.org/doc/manuals/R-admin.html, 
including Appendix C?
(Please keep R-bugs in the recipient list. I'm not the resident expert.)
