But strangely, after I've built and installed ruby if I then do "ruby
extconf.rb" and "make" in those directories, then it builds them!

$ ./configure LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include"
...
$ make
...
$ cd ext/gdbm
$ grep "checking for" mkmf.log
have_library: checking for gdbm_open() in -lgdbm... -------------------- no
$ ruby extconf.rb
checking for gdbm_open() in -lgdbm... yes
checking for gdbm.h... yes
creating Makefile
$ make
...
$ ls -l gdbm.so
-rwxr-xr-x  1 brian  brian  22649 Oct 21 18:03 gdbm.so
$ cd ../iconv
$ grep "checking for" mkmf.log
have_func: checking for iconv()... -------------------- no
have_library: checking for iconv() in -liconv... -------------------- no
$ ruby extconf.rb
checking for iconv()... no
checking for iconv() in -liconv... yes
checking for const of iconv() 2nd argument... yes
creating Makefile
$ ls -l iconv.so

Hmm, so why doesn't that work when building Ruby in the first place?

Brian.
