i386-elf-gcc @4.3.2 Build failure - cannot compute suffix of object files (10.7.2 Lion)

[pugiox@…]

Lion 10.7.2, Xcode 4.2, new install of Mac Ports:

sudo port install i386-elf-gcc

Installs all dependencies fine, then fails with:

Error: Target org.macports.build returned: shell command failed (see log for details)
Log for i386-elf-gcc is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_cross_i386-elf-gcc/i386-elf-gcc/main.log
Error: Status 1 encountered during processing.

The actual error, in the log, is:

Based on some searches it seems that this may be a problem with the install not noticing the 'gmp' and 'mpfr' packages. The recommended fix of explicitly adding the path to those packages in LD_LIBRARY_PATH (I tried LD_LIBRARY_PATH=/opt/local/lib:/opt/local/include) doesn't seem to have any effect.

Attached is the full log.

Apologies, it appears I have duplicated this ticket: ​https://trac.macports.org/ticket/28912 Temporarily changing the gcc and cc symlinks in /usr/bin to gcc-4.2 (instead of the llvm one) solved the problem, as mentioned in that ticket.
