[gentoo-dev] Re: portage compile problem (xemacs)

[Dave Lee]

so in answer to my own question, the reason ./configure was failing is
because I had gpm in my USE variable and so when ./configure was doing its
tests it was adding -lgpm to the gcc command line, and failing to find
libgpm, and not libgdbm.  great.
