But there's a HOLE in the bucket

At $WORK I'm trying to install tmap on 64-bit CentOS 5. Here's how it goes:

• Built RPM for tmap, and it works -- but not using tcmalloc.

• What's tcmalloc? Part of Google-perftools; a faster malloc. We really want tcmalloc.

• Found RPM for google-perftools installed, but includes only the 32-bit version of tcmalloc due to dependence of other parts of perftools on libunwind.

• installing libunwind on 64-bit CentOS 5 a big PITA and I decide to try working around it.

• Conveniently, tcmalloc can be compiled on 64-bit platform; produces libtcmalloc_minimal, which documentation says is perfectly valid malloc.

• tmap does not come, out of the box, configured to look for (in configure script) tcmallocminimal, but there is an commented-out option to do so. You can remove the comment and run autogen.sh, and then configure will look for libtcmallocminimal.

• ...but this fails because the way I compiled/built rpm for tcmalloc does not include libtcmallocminimal.so; includes libtcmallocminimal.so.4.

• and so my half-assed RPM/devel skillz come back to bite me in the ass again.
