［跪求ruby大牛］安装ruby失败，大家来帮忙看看啊
我是这样编译ruby的：

# ./configure --prefix=$HOME/32b/lciahp2/ruby-1.9.1-p243/install --enable-install-doc --without-gcc --enable-pthread
# cd $HOME/32b/lciahp2
# tar xf ruby-1.9.1-p243.tar ruby-1.9.1-p243/lex.c
# cd $HOME/32b/lciahp2/ruby-1.9.1-p243
# touch lex.c
# make


此时出了这么个问题：
  ld -b -o .ext/ia64-hpux11.23/enc/trans/utf_16_32.sl enc/trans/utf_16_32.o -L. -L. -L. -E -lpthread -lrt -ldld -ldl -lm

You have to install development tools first.
