repository から checkout した ruby を out-of-place で build すると、
enc/trans/big5.c などいくつかのファイルが
source directory と build directory の両方に生成されます。
どちらかだけに生成されるのが意図された動作なんじゃないでしょうか。

This appears to have been resolved in the master branch. I ran a similar out-of-place build and ran the grep, and it looks like the transcoders were only built once.
