hm, so apparently R was built with gcc-4.2, but reports gcc as the compiler. 
This seems to be a bug in r-base, then, which will likely also affect source 
package installation. Which version of r-base-dev/r-base-core do you have 
installed? Perhaps you need to forcibly re-install r-base-core/r-base-dev?

Does anybody else use a fresh gutsy installation? If so, could you check
a) the default version of gcc:
# gcc --version
b) the version R was built with
# ldd /usr/lib/R/lib/libR.so | grep "fortran"
c) the version R thinks should be used for compilation:
# R CMD config CC
and post the output?

Same issue, actually, since the 4.1 version of gfortran was used, while the 
4.2 version should have been used.

Ah, indeed. Probably we should add quotes on the line above and the line 
below, as well. I'll prepare a fix, shortly.
