More relevant info:

>getconf LFS_CFLAGS
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

Offending code in procfs.h:

#if !defined(_LP64) && _FILE_OFFSET_BITS == 64
#error  "Cannot use procfs in the large file compilation environment"
#endif

So, somehow the _LP64 macro isn't set.  The only way I could get
around this was to build my extension with -m64.  That got me past the
build phase, but attempting to load the extension then caused ELFCLASS
errors:

>ruby test.rb
../test/tc_all.rb:38:in `require': ld.so.1: ruby: fatal:
/home/djberge/local/modules/ruby/sys-proctable-0.5.2/sys/proctable.so:
wrong ELF class: ELFCLASS64 -
/home/djberge/local/modules/ruby/sys-proctable-0.5.2/sys/proctable.so
(LoadError)
        from ./test/tc_all.rb:38
        from test.rb:1:in `require'
        from test.rb:1

I tried building Ruby 1.8p5 with the -m64 option which resulted in
this:

Any ideas?
