[horde] Help_for_installation

[murali at itechservices.in]

Hi


I have installed debian wheezy 64 bit and followed installation 
instruction from 
"http://www.howtoforge.com/install-horde-5-webmail-for-ispconfig-on-debian-wheezy 
"  and official site of horde and many to install horde 5.2.2. Installed 
php5.4 from debian repository. Also tried with php5.5 from dotdeb 
repository. The problems i am facing as follows

Unable to pecl install sasl
unable to pecl install  lz4 (pecl install says there is no package lz4)
localhost/horde redirects to horde.com with blank page
localhost/test.php is loading with list of missing modules like PAM lzf 
lz4

When i try to pecl install lzf and pam it says already installed


I have also tried with changing the permission of horde directory but no 
luck

How to figure out the issue or is there any installation instruction 
available. Can any one help

Thanks in advance
