bash: /usr/bin/autoreconf: /usr/bin/perl: bad interpreter: No such file or directory - perl

Question

I am trying to compile some software in Windows using MSYS2 mingw64.exe terminal.
On running the autoreconf -i command, I get the error:
-bash: /usr/bin/autoreconf: /usr/bin/perl: bad interpreter: No such file or directory
ls /usr/bin/ doesn't show perl.exe
I remember that perl was installed using some pacman -S command.
As far as I remember, this issue has come up since this month.
(I had reinstalled MSYS2 and Pacman packages thrice this month & the issue does not seem to go. Last time, I had installed all these in May this year & there were no such issues then)
I even re-installed perl in Msys2 and the following output is displayed:
$ pacman -S perl

Still, the same issue -bash: /usr/bin/autoreconf: /usr/bin/perl: bad interpreter: No such file or directory appears
I also tried installing older version(5.28) of perl by:
pacman -S mingw-w64-i686-perl mingw-w64-x86_64-perl
Still the same issue
On further observation, I found out that the perl was getting installed in /mingw64/bin directory instead of /usr/bin.
I tried adding /mingw64/bin directory to the PATH variable as follows:
export PATH="$PATH:/mingw64/bin"
However, the issue is still the same
Please help
