atlas - 3.8.3 - Build 32 bit version even though x86_64 is default in SL

[jameskyle@…]

The generated build command:

"cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_atlas/work/atlas-3.8.3/temp &&  ../configure -C xc /opt/local/bin/gcc-mp-4.3 -C gc /opt/local/bin/gcc-mp-4.3 -C if /opt/local/bin/gfortran-mp-4.3 -C ic /opt/local/bin/gcc-mp-4.3 -C dm /opt/local/bin/gcc-mp-4.3 -C sm /opt/local/bin/gcc-mp-4.3 -C dk /opt/local/bin/gcc-mp-4.3 -C sk /opt/local/bin/gcc-mp-4.3 --cc=/opt/local/bin/gcc-mp-4.3 -b 32 -Fa alg -fPIC -D c -DPentiumCPS=2800" returned error 134

The -b 32 specifies a 32 bit build which then produces errors on down the road like this:

ld: warning: in /opt/local/lib/gcc43/libgcc_s.10.5.dylib, missing required architecture i386 in file
ld: warning: in /opt/local/lib/gcc43/gcc/x86_64-apple-darwin10/4.3.4/libgcc.a, file is not of required architecture
