MATLAB/Simulink (syms) dont work after fontconfig update

I've been wrestling with this issue for a while. Simulink's syms function refuses to work in Matlab (while everything else mostly does) and I think it has something to with fontconfig.

Matlab's error trace:

Error using mupadmex
Error in MuPAD command:

Error in symengine

Error in sym (line 184)
        [~] = symengine;

Error in syms (line 192)
toDefine = sym(zeros(1, 0));

error trace in console:

/usr/local/MATLAB/R2017a/toolbox/symbolic/mupad/../../../bin/glnxa64/mupkern: symbol lookup error: /usr/lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

Not really sure how to fix this, I've tried moving libfontconfig around and creating symlinks but I'm just confused.
Would appreciate any help, thanks.

Re: MATLAB/Simulink (syms) dont work after fontconfig update

Nvm, fixed. For anyone looking to figure it out, remove/rename libfreetype.so.6 and libfreetype.so.6.11 from

/usr/local/MATLAB/.../bin/glnxa64/

Then just symlink your files.

ln -s /usr/lib64/libfreetype.so.6 /usr/local/MATLAB/R2017a/bin/glnxa64/libfreetype.so.6
ln -s /usr/lib64/libfreetype.so.6.13.0 /usr/local/MATLAB/R2017a/bin/glnxa64/libfreetype.so.6.13.

Thanks. The same solution worked for a similar error complaining about:
