Thanks.  Trying again.  The libgmp.a is indeed in .libs as seen here:

mollie:ecm-6.2.1 paul$ cd ../gmp-4.2.2
mollie:gmp-4.2.2 paul$ find . -name libgmp.a
mollie:gmp-4.2.2 paul$


mollie:ecm-6.2.1 paul$ ./configure --with-gmp-build=../gmp-4.2.2
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for signal... yes
checking for malloc_usable_size... no
checking gmp.h usability... yes
checking gmp.h presence... yes
checking for gmp.h... yes
checking for recent GMP... yes
checking if gmp.h version and libgmp version are the same... no
configure: error: 'gmp.h' and 'libgmp' have different versions! you have to properly reinstall GMP.
mollie:ecm-6.2.1 paul$

which is exactly the same error I got on my  very first attempt to build
and why I tried separating out the three options.

(BTW, that's a wonderful split infinitive on the last line.   Should be
"... you have to reinstall GMP properly.".)
