我尝试像这样安装：
./configure --with-erlang=/home/cgenesis/erlang/usr/local/lib/erlang/usr/include --disable-dependency-tracking
make
但这就是我得到的：
./couch_key_tree.erl:78: type boolean() undefined
./couch_key_tree.erl:79: type boolean() undefined
./couch_key_tree.erl:93: type boolean() undefined
./couch_key_tree.erl:136: type boolean() undefined
