I‌ have problem with loading this two important modules in version FreeSWITCH Version 1.7.0+git~20150626T195140Z~2a1195e55d~64bit

I have installed them:
[root@voip freeswitch]# make mod_sndfile-install
make[1]: Entering directory `/usr/local/src/freeswitch'
 /usr/bin/mkdir -p '/usr/local/freeswitch/lib'
 /bin/sh /usr/local/src/freeswitch/libtool   --mode=install /usr/bin/install -c   libfreeswitch.la '/usr/local/freeswitch/lib'
libtool: install: /usr/bin/install -c .libs/libfreeswitch.so.1.0.0 /usr/local/freeswitch/lib/libfreeswitch.so.1.0.0
libtool: install: (cd /usr/local/freeswitch/lib && { ln -s -f libfreeswitch.so.1.0.0 libfreeswitch.so.1 || { rm -f libfreeswitch.so.1 && ln -s libfreeswitch.so.1.0.0 libfreeswitch.so.1; }; })
libtool: install: (cd /usr/local/freeswitch/lib && { ln -s -f libfreeswitch.so.1.0.0 libfreeswitch.so || { rm -f libfreeswitch.so && ln -s libfreeswitch.so.1.0.0 libfreeswitch.so; }; })
libtool: install: /usr/bin/install -c .libs/libfreeswitch.lai /usr/local/freeswitch/lib/libfreeswitch.la
libtool: install: /usr/bin/install -c .libs/libfreeswitch.a /usr/local/freeswitch/lib/libfreeswitch.a
libtool: install: chmod 644 /usr/local/freeswitch/lib/libfreeswitch.a
libtool: install: ranlib /usr/local/freeswitch/lib/libfreeswitch.a
libtool: finish: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/sbin" ldconfig -n /usr/local/freeswitch/lib
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/freeswitch/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

and i configure:
[root@voip freeswitch]# vim /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml

and i have uncommented <load module="mod_sndfile"/>

but in fs_cli when i call module_exists it prints false or calling load mod_sndfile results:
freeswitch@internal> load mod_sndfile
+OK Reloading XML
-ERR [module load file routine returned an error]
