roll back gnucash

[Kastus Shchuka]

Hi,

I just upgraded gnucash to 2.2.0 and after playing with it for some  
time realized that it is not really usable. It starts much slower  
than 2.0.5, report generation takes forever, and moreover, there is  
no graphics in the report.

  Is it possible to revert back to version 2.0.5?

I tried deactivating gnucash using `port deactivate gnucash` and then  
installing old version but it reinstalls version 2.2.0:

sudo port install gnucash @2.0.5_2
--->  Unpacking tgz archive for gnucash 2.2.0_0+guile16
--->  Activating gnucash 2.2.0_0+guile16
--->  Cleaning gnucash

I also tried this command:

sudo port activate gnucash @2.0.5
--->  Activating gnucash 2.0.5
Error: port activate failed: Registry error: gnucash 2.0.5 not  
registered as installed.

What am I doing wrong? Or is it not possible to install old version  
2.0.5 of gnucash with MacPorts?

Thanks, -Kastus
