I was finally able to solve my problem. The reason was the combination of 2 

- CentOS readline library does not declate dependency on curses/termcap
- Samba compile uses the -Wl,--ad-needed link flag

Then, although libtermcap is mentioned as library to link (-ltermcap), gcc 
does not include it - because no directly used library declares any 
dependency on it.

I fixed my problem by using LDFLAGS="-Wl,--no-as-needed" ./configure...... to
