1. 下载gnupg的安装package, 发现下面的网站不错，我要安装东东基本上从这里找。
http://ftp.auckland.ac.nz/sunfreeware/sparc/5.10/
找到gnupg-1.4.5-sol10-sparc-local.gz
2. 上传到unix server 并解压
gunzip gnupg-1.4.5-sol10-sparc-local.gz
3. 安装
pkgadd -d gunzip gnupg-1.4.5-sol10-sparc-local(解压后的文件名)

4. 运行
pgp 安装在/usr/local/bin/ 下
gpg
如果有错误，一般是其他的包没有安装，可以到上面的网站去找，我就遇到下面的错误
ld.so.1: gpg: fatal: libiconv.so.2: open failed: No such file or directory
检查那些包没有：
bash-3.00# ldd /usr/local/bin/gpg
libiconv.so.2 => (file not found)
libresolv.so.2 => /usr/lib/libresolv.so.2
libz.so => /usr/lib/libz.so
libreadline.so.5 => (file not found)
libcurses.so.1 => /usr/lib/libcurses.so.1

libnsl.so.1 => /usr/lib/libnsl.so.1

/platform/SUNW,Sun-Blade-100/lib/libc_psr.so.1
/platform/SUNW,Sun-Blade-100/lib/libmd5_psr.so.1
下载安装这些包后，运行ok.
