Bc and info?

[Scott]

Hi,

A complete newbie just nibbling around the edges of blfs, so excuse
any ignorance.

I installed bc-1.06, and it seems to have over-written
/usr/share/info/dir so that the only "info" item which appears is for
dc. 

The usual questions: WTF? (1) and HITH? (2)

1. Did I miss something? How did this happen?

2. How would I restore the file so that all of the other installed
infos are mentioned again?

Thanks,
Scott Swanson
