Question

我已经定制了自己的postgresql客户端和postgresql client-devel包，我希望它可供Ruby程序员使用。所以安装ruby pg gem的命令如下：

gem install pg  -- --with-pg-config=/usr/local/mypostgres-1.0/bin/pg_config --with-ldflags="-Wl,-rpath,/usr/local/mypostgres-1.0/lib"

如果只安装了我自己的postgresql，那么该命令效果很好。

我的pg_config输出看起来不错：

BINDIR = /usr/local/mypostgres-1.0/bin 
DOCDIR = /usr/local/mypostgres-1.0/doc 
HTMLDIR = /usr/local/mypostgres-1.0/doc 
INCLUDEDIR = /usr/local/mypostgres-1.0/include 
PKGINCLUDEDIR = /usr/local/mypostgres-1.0/include 
INCLUDEDIR-SERVER = /usr/local/mypostgres-1.0/include/server 
LIBDIR = /usr/local/mypostgres-1.0/lib 
PKGLIBDIR = /usr/local/mypostgres-1.0/lib 
LOCALEDIR = /usr/local/mypostgres-1.0/share/locale 
MANDIR = /usr/local/mypostgres-1.0/man 
SHAREDIR = /usr/local/mypostgres-1.0/share 
SYSCONFDIR = /usr/local/mypostgres-1.0/etc
PGXS = /usr/local/mypostgres-1.0/lib/pgxs/src/makefiles/pgxs.mk 
VERSION = PostgreSQL 9.0.0

但是，如果安装了官方和我自定义的postgresql。安装的驱动程序将链接到官方libpq.so而不是我自己的libpq.so。有没有办法强迫ruby-pg链接到我自己的libpq.so？任何线索或提示都将受到赞赏。

如果我不能以这种方式做到这一点，我如何自定义gem链接到我的库？
