espeak在ubuntu10.10下交叉编译的问题

Question

在ubuntu10.10下交叉编译espeak,其中portaudio的版本为pa_stable_v19_20111121.tgz交叉编译成功，并生成相应的库，在编译espeak的时候（espeak为espeak-1.47.05-source.zip），把生成的lib文件夹下的所有库拷贝到/usr/lib和/usr/bin以及/../bin下make，结果还是报错，错误如下：

/opt/x-tools/arm-unknown-linux-gnueabi/bin/../lib/gcc/arm-unknown-linux-gnueabi/4.4.6/../../../../arm-unknown-linux-gnueabi/bin/ld: warning: libportaudio.so.2, needed by ./libespeak.so, not found (try using -rpath or -rpath-link)

这个问题已经困扰我很长时间，请求大神们给点意见，谢谢。
