编译hotspot时出现的错误，求高手解答！

[忍苦]

最近在阅读周志明的《深入理解JAVA虚拟机》,在第一章的时候成功的编译了openjdk，但是接下来编译hotspot的时候出现了一些些问题~。本人使用virtualbox的虚拟ubuntu系统进行编译的。

这是我的shell脚本
#!/bin/bash
export LANG=C
export ALT_BOOTDIR=/usr/java/jdk1.6.0_45
export ALLOW_DOWNLOADS=true
export ALT_OUTPUTDIR=/usr/jvmbuild
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
export DEBUG_NAME=debug
BUILD_DEPLOY=false
BUILD_INSTALL=false
export ALT_OUTPUTDIR=/usr/jvmbuild
unset CLASSPATH
unset JAVA_HOME
cd make
DEBUG_BINARIES=true make jvmg jvmg1

然后再编译的过程中，出现的错误如下
rm -f libjvm.so.1; ln -s libjvm.so libjvm.so.1; \
[ -f libjvm_g.so ] || { ln -s libjvm.so libjvm_g.so; ln -s libjvm.so.1 libjvm_g.so.1; }; \
if [ \"\" = \"\" ] ; then \
if [ -x /usr/sbin/selinuxenabled ] ; then \
/usr/sbin/selinuxenabled; \
if [ $? = 0 ] ; then \
/usr/bin/chcon -t textrel_shlib_t libjvm.so; \
if [ $? != 0 ]; then \
echo "ERROR: Cannot chcon libjvm.so"; \
fi \
fi \

}

查了一下貌似是所谓的文件阻断？然后导致找不到libjvm.so？这个应该怎么解决呢？请求各路大神~
