Player (Robotic server) does not install from AUR

Question

The player robotic server available on AUR fails installation with:
builds/player/src/player-3.0.2/server/drivers/shell/readlog.cc:668:43: error: cannot convert ‘FILE* {aka _IO_FILE*}’ to ‘gzFile’ for argument ‘1’ to ‘off_t gzseek(gzFile, off_t, int)’
builds/player/src/player-3.0.2/server/drivers/shell/readlog.cc:714:62: error: cannot convert ‘FILE* {aka _IO_FILE*}’ to ‘gzFile’ for argument ‘1’ to ‘char* gzgets(gzFile, char*, int)’
From this thread about the failed installation of a different package (Pixie) it looks like it is an error related to the zlib version:   https://bbs.archlinux.org/viewtopic.php?id=136269
The thread mentions how to fix the issue for Pixie, but I don't know how to replicate the solution for player. The offending lines are:
668        ret = gzseek(this->file,0,SEEK_SET);
and
714        ret = (gzgets(this->file, this->line, this->line_size) == NULL);
can anyone help?
Cheers,
Stefano
UPDATE: after visiting the zlib webpage I tried a different tack: downgrading zlib from 1.2.6 to 1.2.5. PLayer now compiles, but it fails at the linking stage with:
/usr/lib/libxine.so.2: undefined reference to `gzgetc_@ZLIB_1.2.5.2'

Answer 1

ALMOST SOLVED:
the file player/src/player-3.0.2/server/drivers/shell/readlog.cc must be changed as follows:
line 668
-              ret = gzseek(this->file,0,SEEK_SET);
+            ret = gzseek((gzFile)this->file,0,SEEK_SET);
line 714
-        ret = (gzgets(this->file, this->line, this->line_size) == NULL);
+      ret = (gzgets((gzFile)this->file, this->line, this->line_size) == NULL);
Now, can anyone tell me how to convince makepkg to use the fixed file instead of the original one?
