Problem installing libxsltmod-1.5a

Hello,

I am having difficulties installing the libxsltmod-1.5a package.

I9ve tried to install it trough easy_install but it failed at the following
errors:

libxsltmod.c:28:30: error: libxml/xmlmemory.h: No such file or directory
libxsltmod.c:29:29: error: libxml/debugXML.h: No such file or directory

/usr/include/libxslt/xsltInternals.h:21:30: error: libxml/xmlstring.h: No
such file or directory
Etc........

I have the following specs:

OS: Ubuntu 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:48:10 UTC 2009 i686
GNU/Linux

Installed the libxml2-dev & libxslt-dev through the package manager:

apt-get install libxml2-dev libxslt-dev

It seems it can9t find the files so I9ve added the /usr/include and /usr/lib
to the path but it didn9t mattered.

Please help!

Thanks
