[gmx-users] problem with compiling fftw

  When trying to compile fftw3.3.3 in our cluster I got following error. Apparently, it try to guess the build-type by trying to create a directory in scratch. I am not sure why it will try to create a directory there and then it fails. I was wondering whether there is any way-out to avoid this issue. Is there any way in a machine to know its build type and if so, what is the option in fftw to mention the directory.
Below is the error message.

./configure --prefix=/home/joe/UTIL/fftw/ CC=gcc  --enable-float
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether to enable maintainer-specific portions of Makefiles... no
