Firefox 1.5 + Flash 7, "_dlsym" symbol... again

[Norberto Meijome]

Hi there,
firefox-1.5.0.1_1,1  built from source
linux-flashplugin-7.0r63 
flashpluginwrapper-0.20021113_1 

6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #0: Mon Mar 27 11:43:54 EST 2006

(flash v.6 is marked as with security vulerability)

I have followed the steps that had got flash6 working in another
machine. firefox shows the plugin in in about:plugins

When I go to a page with flash, firefox dies with:

/libexec/ld-elf.so.1: /usr/local/lib/pluginwrapper/flash7.so: Undefined
symbol "_dlsym"

This is with and without the suggested patch. I did:
$cd /usr/src
$fetch http://people.FreeBSD.org/~nork/rtld_dlsym_hack.diff
$patch < rtld_dlsym_hack.diff

$ cd libexec/rtld-elf
$sudo make rtld

$ sudo make install
---

Any suggestions on how to fix this ?

Thanks!
Beto
