[ale] cannot find -ltdl

[John Wells]

Guys,

Trying to compile php on a RH 9 box, and have run across an error I've not
seen before:

/usr/bin/ld: cannot find -lltdl

Problem is, the library seems to be there:

[root at liberator php-4.3.3]# apt-cache search ltdl
libtool-libs - Runtime libraries for GNU libtool.
libtool-libs13 - The GNU libtool, which simplifies the use of shared
libraries.
[root at liberator php-4.3.3]# rpm -qa | grep libtool
libtool-libs-1.4.3-5
libtool-libs13-1.3.5-7
[root at liberator php-4.3.3]# rpm -ql libtool-libs | grep ltdl
/usr/lib/libltdl.so.3
/usr/lib/libltdl.so.3.1.0
[root at liberator php-4.3.3]# locate libltdl
/usr/lib/libltdl.so.3.1.0
/usr/lib/libltdl.so.3
[root at liberator php-4.3.3]# file /usr/lib/libltdl*
/usr/lib/libltdl.so.0:     symbolic link to libltdl.so.0.1.2
/usr/lib/libltdl.so.0.1.2: ELF 32-bit LSB shared object, Intel 80386,
version 1 (SYSV), stripped
/usr/lib/libltdl.so.3:     symbolic link to libltdl.so.3.1.0
/usr/lib/libltdl.so.3.1.0: ELF 32-bit LSB shared object, Intel 80386,
version 1 (SYSV), stripped

The files are definitely there.

Just to make sure, I checked to see if ld knows about them:

[root at liberator php-4.3.3]# ldconfig -p | grep ltdl
        libltdl.so.3 (libc6) => /usr/lib/libltdl.so.3
        libltdl.so.0 (libc6) => /usr/lib/libltdl.so.0

Now, I'm at a loss.  I've searched google for awhile now and haven't run
across a valid solution.

Can anyone see what I'm missing here?

Thanks!

John
