LDFLAGS="-lm" emerge pengupop is needed to get it working Reproducible: Always
Created attachment 369044 [details, diff] pengupop-2.2.5-underlink.patch I'm surprised the current underlinking patch even works, seeing its adding -lm to _LDADD under the DARWIN conditional. Anyways, I've added a standard AC_SEARCH_LIBS to configure.in as it should be.
