Problem after installation

[Markus Popp]

Hi!

First of all ... Linux is quite new to me and I hope the cause of my problem 
isn't rediculous.

The installation of v. 1.4.9 seemed to work fine but when I tried to start 
the file /usr/bin/gnucash (with both normal user and root) I got a message 
which said 'gnucash: error while loading shared libraries: 
/usr/lib/libguile.so.9: undefined symbol: qt_error'.

Do you have an idea what could be wrong and how the problem could be solved? 
Please let me know ;-). Thanks in advance!

Regards,

Markus
