I'm trying to build Guile 2.2.0 on CentOS 7.3 with GCC 4.8.5. During configure, I see the following error message:
checking for libltdl... no
configure: error: GNU libltdl (Libtool) not found, see README.
I do have libtool installed on my system:
$ which libtool
/usr/bin/libtool
$ libtool --version
libtool (GNU libtool) 2.4.2

I'm passing the following option to configure:
$ ./configure --with-libltdl-prefix=/usr
but it still doesn't pick up libltdl. Based on the following help message:
$ ./configure --help
...
--with-libltdl-prefix[=DIR] search for libltdl in DIR/include and DIR/lib
I believe the problem is that CentOS installs libltdl to /usr/lib64 instead of /usr/lib:
$ ls -l /usr/lib64/libltdl.so.7*
lrwxrwxrwx 1 root root 16 Feb 27 11:19 /usr/lib64/libltdl.so.7 -> libltdl.so.7.3.0
-rwxr-xr-x 1 root root 41248 Feb 16 2016 /usr/lib64/libltdl.so.7.3.0
Do you have any suggestions as to how I can get Guile to pick up libraries installed in /usr/lib64?
