Hello Foxill1 (?)
Looks like your build environment can't find the BerkeleyDB include (&/or library) files, perhaps other things too!
So you must ponder your build machinery, autogen? and the system it is running on (your OS setup) and try to determine where &/or who is wrong.

I would look at message #1 in this forum,
https://bitcointalk.org/index.php?topic=149479.msg1587734#msg1587734, especially step 2.2

one more question. How can I change the look wallet? Qt Creator does not help
