I am trying to compile /stunnel-4.04 and I am having this problem with the configure exiting because opf something it can not set

I've been reading around and this seems to be a problem with libiconv, but I have it installed, I have attached the configure.log for review

bash-3.2# swlist -l product|grep -i lib Libiconv 1.6.1.16 Libiconv - Character set conversion library libiconv 1.12 libiconv

I dont wkat else is missing, I am running this on HP-UX 11.31, I would appreciate in advance any help or hints, thanks folks
