PyCrypto 2.7a1 build fails on Solaris 11.1

Host is Solaris 11.1 clean install:

uname -a
SunOS <cut> 5.11 11.1 i86pc i386 i86pc

Problem #1:

prompt $ /path/to/install/bin/python3 setup.py build
running build
running build_py
running build_ext
running build_configure
building 'Crypto.PublicKey._fastmath' extension
gcc -std=gnu99 -g -fwrapv -O3 -Wall -Wstrict-prototypes -g -O2 -Wall -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -DHAVE_CONFIG_H -fPIC -Isrc/ -I/path/to/install/include/python3.3m -c src/_fastmath.c -o build/temp.solaris-2.11-i86pc.32bit-3.3/src/_fastmath.o
src/_fastmath.c:34:18: fatal error: gmp.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1

GMP is installed with the package manager, but in Solaris 11.1 the include file is under a subdirectory:

prompt $ ls -l /usr/include/gmp/gmp.h
-r--r--r-- 1 root bin 84701 Oct 27 2012 /usr/include/gmp/gmp.h

Problem #2.

Configure without gmp:

prompt $ ./configure --without-gmp
<OK>

prompt $ /path/to/install/bin/python3 setup.py build

running build
running build_py
running build_ext
running build_configure
