Since my OpenBSD install doesn't use X11 I couldn't use the official Pidgin package and had to install by source instead. To start out, I used the following configure command:
./configure --enable-consoleui --disable-gtkui --without-x --with-python
Which resulted in the following error:
...
checking for initscr in -lncursesw... no
checking for update_panels in -lpanelw... no
checking for initscr in -lncurses... yes
checking for update_panels in -lpanel... no
configure: error:
Finch will not be built. You need to install ncursesw (or ncurses) and its development headers.
