jwhois requires an iconv implementation. On non-glibc systems, GNU libiconv provides it. However, even when libiconv is detected by configure, jwhois fails to build at the linking step with undefined symbols to libiconv_* functions. Alpine Linux has a patch for that and I simply use it.
Steps to Reproduce:
1. Install Lilblue
2. emerge jwhois
jwhois installed on system
