devel/cbindgen compilation error

[Mayuresh <mayuresh%acm.org@localhost>]

In pkgsrc current firefox dependency led to cbindgen compilation error.

   Compiling serde v1.0.64
error: Shared object "libproc_macro-14c6c250e3e06672.so" not found
   -->
/usr/pkgsrc/devel/cbindgen/work/vendor/serde-1.0.64/src/lib.rs:283:1
    |
283 | extern crate serde_derive;
    | ^^^^^^^^^^^^^^^^^^^^^^^^^^

error: Could not compile `serde`.

Any way to get past this?
