Dave, > Compilation failed on xxx.xxx.edu<http://xxx.xxx.edu> (Mac OS X v10.8). I’ve > attached config.log, configure.log, and make.log files. Congratulations! You've won the weirdest error award! Seriously, I've never seen this one before: > Making install in basics > ../../regutil/substPaths <configuring.html.in >configuring.html.tmp > sed: RE error: illegal byte sequence I suspect the sed(1) utility you're using doesn't conform to the standard. From the file "config.log", I notice your PATH environment variable is a little odd: > PATH: ./ > PATH: /opt/local/bin > PATH: /opt/local/sbin > PATH: /usr/local/bin > PATH: /usr/bin > PATH: /bin > PATH: /usr/local/sbin > PATH: /usr/sbin > PATH: /sbin > PATH: /usr/X11R6/bin > PATH: /usr/local/unidata/ldm/decoders > PATH: /usr/local/unidata/ldm/util > PATH: /usr/local/unidata/ldm/bin > PATH: /usr/local/unidata/ldm/scripts > PATH: /usr/local/unidata/scripts_isl > PATH: /usr/local/unidata/wxp/bin > PATH: /usr/local/unidata/wxp/scripts > PATH: /usr/local/unidata/scripts_m100 > PATH: /usr/local/unidata/bin > PATH: /usr/local/unidata/ldm/ramadda/ramaddaserver > PATH: /Applications/IDV > PATH: /Users/wrf/WRF/scripts > PATH: /Users/wrf/WRF/scripts/precip > PATH: /Users/wrf/WRF/scripts/stat_analysis In particular, the directory with the standard-conforming utilities, /usr/X11R6/bin, is after directories whose utilities might not conform to the standard. If you would, please move /usr/X11R6/bin to the head of PATH and try again (after a "make distclean", of course -- better yet, remove the entire directory hierarchy and unpack from scratch). Also, having "./" near the head of PATH can cause problems. I recommend leaving it out of PATH altogether -- or at least moving it to end. Please let me know what you find.
