Building slang broke on my system complaining about unknown symbols 'setfsuid' and 'setfsgid'. Looking at the ebuild I found to my surprise patches catering for that. However, autotools related files are patched, but autoreconf is not rerun afterwards.
The attached patch fixed the issue.

Patch for the slang ebuild to made it work on my system
Without applying any patch, it compiled fine on my 10.4/PPC machine...
Pipping can you try on x86-macos?
compiles for me, with all possible combinations of the USE flags cjk and unicode.
please give some more detailed info about your system (emerge --info?) and the logs of what happens when you emerge slang.
Weird. Now it works for me as well. I can't reproduce the issue.
I may have been running this emerge in a messed up shell environment.
Sorry for consuming your time then.
