Installing Firefox 38.2.1...?

I don't want to be a nuisance or start a prolonged thread, but I really 
need some help in getting a recent FF to run. First I install eCS22b2 
including RPM/Yum. Then I install the ANPM. Then I open the readme.os2 
from FF38.2.1 and install all the listed packages, using ANPM.

When I selected freetype to install ANPM said that I first should remove 
certain dll's that were presently in use. How do identify and remove 
these dll's?

ANPM cannot find Pango at Netlabs repository. I suppose I must create a 
platform file in x:\etc\RPM\ containing the entry "i686-OS/2-OS/2", and 
then use ANPM to install Pango. Is that right. Could I just copy some 
dll's somewhere, maybe x:\ecs\dll?

Will I still need some more packages to get FF 38.2.1 to run?
