linux - "configure: error: mcs Not found" during configure mono-addins on CentOS -

-

i'm trying install monodevelop 4 on centos 7 described in post: install mono , monodevelop on centos 5.x/6.x, when i'm trying execute ./autogen.sh --prefix=/usr in mono-addins src directory, error: 

running autoconf ... running ./configure --prefix=/usr ... checking bsd-compatible install... /usr/bin/install -c checking whether build environment sane... yes checking thread-safe mkdir -p... /usr/bin/mkdir -p checking gawk... gawk checking whether make sets $(make)... yes checking whether make supports nested variables... yes checking whether uid '0' supported ustar format... yes checking whether gid '0' supported ustar format... yes checking how create ustar tar archive... gnutar checking whether enable maintainer-specific portions of makefiles... yes checking pkg-config... /usr/bin/pkg-config checking pkg-config @ least version 0.16... yes checking gmcs... no configure: error: mcs not found

mcs compiler installed successfully, , if execute

mcs --version

it returns

mono c# compiler version 4.0.3.0

in other examples of autoconf output see checking gmcs returns /usr/local/bin/gmcs or /usr/bin/gmcs, on system after compiling mono don't have gmcs @ all.

what difference between mcs , gmcs, , can find second?

mono-gmcs interim compiler before moving mcs. ran problem ("configure: error: no gmcs c# compiler found") while trying install bless (a mono/c# hex editor) on centos 7. not sure if answer on other distros, added symbolic link ln -s mcs gmcs, script looking gmcs find it, redirect mcs, current mono c# compiler. both should in /usr/local. bless, there dependency on "scrollkeeper", took care of yum install scrollkeeper.
