What OS and hardware is this? Eventually you mention `X86 Linux' but are
you using x86 Linux and if so how fast processors? On a 3GHz machine make
check takes a couple of minutes using gcc (and in our experience Portland
Group is faster than gcc -- we have not tried Intel as local advice
suggests it is slower than PG).
Which version of R? R 1.9.0 does this with gcc 3.4.0 on Linux ix86, at
the first use of LAPACK. So if you are not trying 1.9.1beta (to be
released on Monday), please do so. After that, make check does give
output so where exactly does it hang, and if you interrupt that check, how
far has it got in the output file?

Did you search the archives? I found a lot of hits, none recent for ix86
