7.1.3CE install fails on CentOS 5.7/32 under Xen

Though hopefully, "under Xen" is immaterial.

The whole stack is 32bit cause the hardware won't virtualize 64; CentOS cause that's what I have. That said:

Never run across this category of failure on a fresh install, that I can remember. Any suggestions?

As it turns out, the source of this error pattern is that my downloads directory is remote-mounted noexec. For some reason, it let me run the main install.sh script, but started failing immediately, when that called other scripts in the install tree. Taking noexec off the mount solved the problem.
