今天折腾了四个小时才把这个正确安装上，特此记录下。特别感谢群友的支持。
在VMware上新安装了Debain7.5，具体细节不复述了。
一、更新系统
#apt-get update
#apt-get upgrade
二、构建编译环境
#apt-get install build-essential
#apt-get install automake autoconf
#apt-get install bison gettext libtool libglib2.0-dev libfreetype6-dev libfontconfig-dev
（最好一个个地执行，保证安装成功）
三、安装其它库文件
#apt-get install libgif-dev libtiff4-dev libpng12-dev libexif-dev libx11-dev libxft-dev libjpeg-dev（也是最好一个个地执行，保证安装成功）
四、下载源文件及解压
#wget http://download.mono-project.com/sources/libgdiplus/libgdiplus-2.10.tar.bz2
#wget http://download.mono-project.com/sources/mono/mono-3.4.0.tar.bz2
#tar -jxf libgdiplus-2.10.tar.bz2
#tar -jxf mono-3.4.0.tar.bz2
五、安装libgdiplus和mono
1、安装libgdiplus
#cd libgdiplus-2.10
# ./configure --prefix=/usr
#make
#make install
cd..
2、安装mono
#cd mono-3.4.0
#cd mcs/tools/xbuild/targets
#cp Microsoft.Portable.CSharp_4.0.targets Microsoft.Portable.Common.targets
#vi Microsoft.Portable.Common.targets
将<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />去掉之后保存退出
#apt-get install mono-gmcs
#cd
#cd mono-3.4.0
# ./configure --prefix=/usr
#make
#make install
#cd..
至此 mono -V查看版本

六、安装jexus
#wget http://www.linuxdot.net/down/jexus-5.5.2.tar.gz
#tar -zxf jexus-5.5.2.tar.gz
#mv jexus-5.5.2 /usr/local/jexus
#cd /usr/local/jexus
#./install
Installed /usr/jexus/jxAspx2.dll into the gac (/usr/lib/mono/gac)

接下来就准备把devtext往mono上迁移了
