I can't reproduce the issue on a similar setup.

It really looks like a glibc cockup here. So I'll reassign to the toolchain
guys in order to get their opinion.

Denis.

looks to me like gpsim sucks

it uses libdl functions in src/ but never explicitly declares -ldl in LDFLAGS
... it assumes that the X_LDFLAGS variable will include -ldl from packages like
gtk and gthread

update src/Makefile.am and add -ldl to libgpsim_la_LDFLAGS

Created an attachment (id=86736) [edit]
gpsim-0.21.11.ebuild

Here's an ebuild that should solve the issue. Please try it and tell us if it
does.

Denis.

Fixed.
