SVN 1.6.6 compilation error

[Rodrigo Goncalves <ro...@cflex.com.br>]

Hello ALL,

I am trying to compile SVN 1.6.6 on a linux machine.
After resolving all dependencies and running the ./configure, I am  
getting a strange error at make:

(...)
/bin/sh /root/svn/subversion-1.6.6/libtool --tag=CC --silent -- 
mode=compile gcc -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -

I have no idea how to solve this.
No luck at Google...

Please help!

Tks,
Rodrigo.
