Ohh, as simple as that  ;-)
If we then to this problem add that there is a possibility two plugins, 
two dll packages,  are active in SportTracks (one is the one I am 
developing) that both depends on GDAL but on different installations 
(possibly different versions). Will the path I set pollute the second 
plugins path? If we say that both plugins use the same method as in the 
example above and not have the DLLs in their local directory.
Should not be a problem I think, but without asking I can't know for sure.


Thanks!
