前两天在CSDN求助这个问题了，正好现在查到了原因，写一个笔记，着实纠结了一下午。
出现错误：
/opt/openoffice.org2.0/program/javaldx:
/lib/i686/libpthread.so.0: version `GLIBC_2.3.2' not found (required by
/opt/openoffice.org2.0/program/libuno_sal.so.3)

有时就干脆卡掉了

我把回答也贴出来：
1) RHEL 5.5 is an old version. The current update is 5.8.
2) Openoffice 3.4 is meant for an OS later than 2007.
.... An OS with at least glibc-2.7.
3) RHEL 5 is based on packages from year 2006. ( Fedora 6.)
4) Glibc-2.5 is your OS ( together with the kernel )
.... and cannot be replaced.
