dev-db/libodbc++ underlinks `/usr/lib/libodbc++`. A hand-build libodbc++ depends on libodbc, but the one from the ebuild does not (probably due to -Wl,--as-needed somewhere). This leads to suprising link failures, e.g. $ cat test.cpp int main() { } $ g++ test.cpp -lodbc++ /usr/lib/gcc/i686-pc-linux-gnu/4.4.5/../../../libodbc++.so: undefined reference to `SQLFetch'
